Free Lincoln Welder. Can We Save It?

trash pick from the side of the road wait gets better you came with the owner's manual so hey guys how's it going so this was in a free pile on the side of the road along with some other junk i left the other junk behind but i ended up grabbing this and over in the one of the garbage cans was the manual for two so i figured we'll bring it back to the shop put it up on the bench and we'll see if we could figure out why it was thrown out what it failed for possibly if we could fix it don't have any idea so let's get into it see what we find let's quickly just see what's inside here got a tip and an allen wrench you can tell this is gonna be an older one it's got a vhs tape and is any of it just actual manuals or is it just do not do stuff warranty is not filled out what does this tell us anything i just had to use it no uh okay let's look at the welder let's go flip it to the side see what it looks like on the inside we got bits you got more tips and what is that so i'm gonna call it a mig welder it's not really a mig welder it could be a mig welder uses gas in a uh i know you want to call it is a flux core setup flux core is it does not use gas but it uses a wire that is coated well internally has a flux in it this wire is hollow see what we got on there 35 yeah cord wire near gas so on the inside of the wire is like a flux and as you weld with it it makes a shielding gas when you weld oxygen is your enemy so you need something to have a cloud around the puddle where you're welding to keep the weld puddle from getting contaminated normally you do that with a welding bottle and a gas or like i said flux core is kind of doing the same idea but it's creating its own shield from the oxygen using the flux that's in there all right enough of that so yeah here it is set up on here so uh flux core you gotta change your polarity and if you use it as a mig welder you flip the polarity over and then you have a gas that goes with it and what's got on it for a tip it does not have the shielding tip on it so this is just set up for flux core it would have a nozzle on the end of it with uh air space around it for the gas to come out i see we got a little rust on the feeder plug it in in a second we just give ourselves a quick overlook how's anything out of the ordinary with it those look terrible and just looks like it's dirty from sitting around that's just a date on 87. that wouldn't make sense i'm seeing it it has a vcr tape in it and we just got for output that's pretty low they this is a transformer welder and they have what's called a inverter welder which is more the modern stuff that's coming out inverter uses i'm going to call electronics where this uses a transformer to uh make the power from ac to dc and then it again i adjust across the transformer where a inverter is more of an electronic exchange you get a lot more out of an inverter for the same amount of power going in but this is where it all started with so this weather will probably be three times as heavy as the inverter welder too so what do you say it is 110 or 120 volt we'll go let's just go plug her in see if it does anything all right it's in the off position we'll see him back from it a little bit just in case he goes poof shall we [Music] made some kind of weird noise doesn't it sound like it's like buzzing like electrical buzzing i don't want to touch it smells a little funny too let's go uh that's good puts wire out i wonder if there's something stuck in the fan that might be what it is sir we'll get ourselves a piece of metal and a welding helmet too if it does anything all right watch your eyes that sparks i'm exactly called smooth well the transformer part at least is working what's um she probably a little less a little less wire it's good you can crank her up a little that that might be where the fault is right there the crank up does not crank up you guys see it does not change positions it's a joke there we'll give it a little throw for a second it seems like it's all the way up like being on b should be like the lowest power i think and it's burning through it seems like it's because this is only a 110 well it doesn't put out very much it seems like [Music] what it's doing full power but it's on b yeah i'm gonna break it if i try going any further it's gonna break so maybe that's why i was thrown out all right let's go shut it off and uh let's get the skins off of it so you can get towards that so this thing has big capacitors in it too so we got to be a little careful that uh you know electrocute ourselves when they're in there but let's get in so it looks like we take just all these out of it we'll be able to get this part of it off i don't know if that lip goes up over it or not i hope that front has to come off [Applause] i don't really see are they capped off how would that face come off let's get these out of here and see if it'll just kind of pull up and out of the way think it'll go that was hard cool all the innards you can get a wiring diagram on the inside of it let's get you out of the stand let's see we got i don't see anything smoked that'll get you that's a big capacitor right there stores energy yeah i don't see any like mice or anything in it i wonder if it's just so it's that selector right it's it's that one the one the top one turns feed rate this is the power that it puts out that one's stuck in one position i wonder if it was just you used on one spot so long that it the tabs kind of welded themselves together looks like it's got a sweep let's get that closer yeah that there's a there's a pad and just making contact with different spots can it seem like it was putting a lot of voltage out there for being just on b usually these things just barely make it what they're supposed to let's get a light on there i'm also going to uh short out across that capacitor in case there's anything in there we're going to let it discharge this could suck jeez i'll tell you yes i was a little on the paranoid side okay good so there's nothing in that capacitor stored i don't see any other ones on it real quick it's on the other side of that actually we can't that's just the uh spool right yeah that's the only cap that's there okay let's get i wonder if we can like unbolt that pull it away maybe we can get let me go get a little light we're going to look right inside there where that tab is on the pad let's see if we can so my thought is that little pad you can see that little pad right there it's welded to the one that it's on let's swap that i'm gonna try turning it no cuz because that's moving oh that's not frozen so something else is causing it not to want something broke on it that looks pretty nasty right there that see if we can make that light stay hold on one sec let's try it again it moves but not man oh it's going it's going i'm gonna break the knob off though i'm giving it a lot it's weird though because like that distance there's no restriction on it so it's not like that the shaft in the middle is bound up that part is turning free it goes man that's that's crunchy though i can't get to go to the next one so something's definitely wrong now i don't know if you got to go see those little notches down there right under there those little like cams that locks it into different locations i wonder if you should probably just throw me a little lube on there where those cobwebs are yeah let's try dripping a little bit of like machine oil down inside there and see if that'll yeah yeah let's go throw a little bit of oil on there and see how well this works out for us i think i want it right yeah i'm not going to go overkill i don't want to get it on the contacts you know they're meant to kind of stay dry let's see if that'll click for us a little better it's gonna have to we're gonna have to get it to go once at least to oil everything yeah that's not it let's i don't know can we get the knob off the front maybe i have to pull it right out of there sometimes there's a set screw in the knob itself on the side you can take the knob off and we can get the bolts out of the out of the side of it might be in the heel i might just pull straight up too let's go get a little uh what about this one see that one's got a set screw on it if you can see it i don't see one on the other one though let's see if we can get that off [Music] yeah is that the only thing holding the whole thing on could be more than that right yeah that's it wouldn't trust that would you i'm gonna get that out of there see what it does so if this thing's in 86 i bought my first welder it was from sears and it just had a high and a low switch and i i think i had a feed control when but it was just high and low that's all it had and nothing would barely weld a piece of metal let's see if that's moving anything it was expensive at the time i want to say they were like 200 bucks and sears had a super sale on it for like 120 that was big money back in 86 that's like spending i don't know four or five hundred dollars now i didn't have that kind of money but i needed to weld and i used that thing forever and i'll tell you one thing that makes you a good welder it's a shitty welder because you have to do everything with whatever that can produce now with all the offshore ones it's really gotten pretty cheap i don't see it was all kind of built together do you better can we get the front panel off well it's going to help us though if we could leave the switch where it is it's your thoughts i want to try to get to it because that that's just plastic it was just like on the verge of cracking on us and i don't want to uh you know kill it because everything else seems like it's working pretty good uh i'm gonna go study it for a little bit i don't know if we can get maybe is that gonna help us that's just gonna take the skin off right yeah nothing's holding it it's it's free that little screw is the only thing holding it so look at that a little bit more you can see a screw coming through on the front side of it there so i think if we get this front cover off of here there's some other screws that we can kind of get i'm trying to just try to make some room possibly we can leave the switch where it is if we can get the front panel out of the way is what i'm hoping for yeah let's get this off you get that screw out of there now you know when something's really old in the united states it's got standard hardware on it it's not metric there's that i'm probably going to take that nut off and then the rocker switch we just pull the wires off yeah i don't think they have a polarity to them pop them off [Applause] that let's go get a pair of pliers for that yeah then after that welder i think it finally died before i just got enough money i was able to replace it and that ended up i got the it was a lincoln but it was a 220 volt it wasn't you couldn't switch it i still have it actually today and that was uh a little bit on the opposite side because it ran it it was just 220 and it still had the same selector switch so you kind of have problems with trying to get the power to be right in between different thicknesses the metal it never seemed like it was had a great combination some of the better ones i think with lincoln uh if it says hd on it meant home depot and if you bought it from like a lincoln dealer instead of it having like this one has where it's got a selector switch for power it had a a variable one on it so you're able to dial in the power much better if we have to take the the gun off of it the cable let's just see and see if this pulls back a little it's going to make us fight for it it might work but we're going to fight for it let's get the we got to get the let's throw that anywhere that's out of the way let's disconnect we can get the wire out of it and we'll take this out of our way i think that's what's holding us right now so this should just kind of flip down this puts tension on the you can adjust the tension on the wire going up we should able to back that up now maybe all we got to do is uh cut the other end off i'm going to just unthread it yeah you see i went through okay good let's go cut the little blob off the end we should be able to there we go that's all going to get cleaned up anyway that roller's looking pretty crappy actually the wire is not looking very great neither steal a bunch of rust i'll show you miles long is it i want to make sure you don't let go should that just on thread or does it have like a there it goes it came out kind of pukey i'm gonna go poke that through in one of the holes keep it from undoing itself good look i want you to see it on the wire itself the rust that's the spool's got a bunch of rust on it there you go there's a whole ton of it right there that's been sitting in a while oh you suck [Laughter] oh you suck that's always trying to avoid that i'm gonna wind that up what's this stuff it's just a it looks like the plastic just degrading oh maybe it's the paper from the back i don't know maybe it's the paper from right there so the gun has a trigger you pull the trigger that's what tells the welder to make power into feed wire that's what these two wires are and then that little wing nut should be just the only thing that's holding the wand in see if that would come out of there there we go yeah and if you had gas there's a little hole right there that's where the gas would get fed in through and down the the center of the hose here and there's the where the tap where the line would go in and that would be on a separate setup going through the back of the machine and would feed out of there the bottle would feed into here let's see if he even has any of that stuff on it no so this really can't be converted over to uh [Applause] a mig an actual make it's more just a flux core welder [Applause] and i found the noise that we're looking at in the fan what's that right there that that was a noise get that out of there it sounded like electrical zapping when i was doing it though was it like a cigarette pack thing i think that's what it is it's gonna break on me oh yeah a couple little tweezers or a hook so you can hook that in there i think it's kind of tied up on itself maybe that's the way they got rid of it too maybe they thought they heard a electrical zapping noise yeah i think that's it for a cigarette pack isn't it how long ago i don't even know cigarettes even sold like that still will you pull the little foil off i've been there forever quiet now all right back to where we were and see if that face will pull away we got tape around the capacitor [Applause] holding that on nice high tech doesn't it it's definitely strong enough that's for sure there goes the warranty there you have it now come on [Applause] i think we're gonna have to these two yeah we're just gonna end up just tearing the whole thing apart okay there's the polarity you're gonna remember the the one that goes this is yeah i must discuss that so on the difference between flux core and a mig is polarity also you have to change the polarity around it's got a positive and a negative only it just shows up there's a positive negative in the middle so positive is it looks like negatives going to the gun the outside of the gun so we'll remember that this is the bottom one probably going to bounce back in that same spot anyway but let's go see if we can two more i think it says tested 87 on it if i say 86 great tool for the right job fight me will you so that's just not happening without breaking i guess it's gonna fight me like it said it said challenge accepted as it thoroughly kicks my ass yeah they probably have the little ends on them that's spread out once they're through you got to kind of pull them together hmm they have to come out they're just ribbed ribbed for her pleasure they're gonna they're gonna snap but we'll put new ones in pull teeth definitely didn't want them to come apart and came out like half of them halfway there we go all this and it still won't be where we're the direction we need to take it up to get it out i also want to unsolder those wires you know yep sacrificial lamb all right we in finally what else we got yeah you can get to the switch now almost kind of looks like that'll lift off there doesn't it so i would think i don't know what that screw does for us take that out i want to try to get this to back off this i'm going to call it bakelite it's plastic this is what it's going to snap on us let's go shove where'd the knob go that's the one we want yeah watch it turn no problem now i wonder if so it needs to be able to squeeze this way so that spring has to be able to collapse so that it can come up over that cam that's probably what's not happening there it goes yeah i think so much corrosion like that that white plastic's got like a that's what's going on the white plastic has a bunch of um punkiness do i wonder if it just sat for so long there it goes yeah so this white scaliness let me get a poker see all this white on the outside of it here it's like corrosion on the plastic and it seems like it's made it tight down the center there can we come on i wonder if we can get behind it now with a little bit of lube down inside there if not i actually can take the knob off right can we lift that right out of there where's that now it hits a stop yeah it's not going to come out anyway it's back far enough let's go try shooting a little bit well down in there again i don't want to get too much by the electrical parts but we got to do what we got to do right probably feeding on the other end too but we got to get let's turn it back on there you go that doing it it's all she needed lube in the right places to bring her back to life right i'm gonna work on trying to improve that just a little bit she's still you hear it right oh that screw is just a stop so you can't go any further it's the last little last location on the tab all the tabs look pretty good yeah originally i thought it was going to be like arc welded to one of them yeah it looks pretty good yeah it screws just to stop so it doesn't go any further all right i am going to work on trying to just clean that up a little bit better in there to get that to rotate a little bit better i'll blow it off with air maybe a little bit of uh contact cleaner just get rid of the the crap on the outside again i just don't want to get any oil towards any of these i like it hurt i think what it'll do though if you get oil on it kind of like on points it'll cause the contacts to burn if they get oil in between them yes i worked a little bit more and seems pretty good i don't know much more i can do you know try to remove that all together i have a feeling if i do that i'm going to break something i think we're better off just trying to work with it where it is and it's enough to you know raise that detent up more than enough all right well i'm gonna go put it all back together and you guys don't need to watch that part of it and hopefully when you put it back together there's more i think i had a whole cigarette pack inside there anymore while we're looking yeah it's sitting right there i don't know where that fell out of a little moth okay nothing to do but put all those pieces back in there that's about halfway back together that works a lot better oh yeah good and our speed works we have to [Applause] deal with that roller let me get you a closer so that roller right right there is what feeds there's a little electric motor behind that and that is what feeds the wire through at the selected speed you can see there's actually two grooves on this one closer to you which is real thin and there's a the back one with the teeth on it is for the heavier wire and that's it's on the correct one you take that spool out and spin it around for which diameter that you're running we have to get the rust off of that it's looking pretty nasty and so we have to power it up we'll plug the the wand back in see if everything works we'll hit the trigger we'll try to get it so that that little spot is facing up where we can allen wrench on there and take that off of there i plugged it in that's good i got the gun just kind of plugged in it's not hooked up yet we should about hit the trigger though there shut it off let's even get a little allen wrench and it might be the same one that held there we go it'll come off there and a little credit i'm going to go take that on the wire wheel i'm going to get rid of all that beaked on rust there it's definitely sat for a long time oh that's really bad right there yeah let's go get that cleaned up [Applause] we should probably get that roller out of there too i don't that'll just pop out kind of looks like a wood doesn't it yeah that's got a lot of rust on it that's the other half that feeds on it but it coast the other one's driven but this is the you know the idle half of it's what puts put tension on it i think we're gonna have to get a beefier screwdriver yeah we'll start with a heavier pick and that doesn't work well let me just push from the top i don't want to break the plastic they're so close you know i can get that right out of there i'm afraid i'm going to do more damage by screaming i think i'm going to go get a little wire wheel and we're going to go dress it right where it is i think if i try getting that out of there i'm going to break that plastic i just clicked back into place too come on you come out of there ah we got it yeah let me go clean the rust off of that bearing feels pretty good i'll snap in there come on all right so i think we're good as far as that's concerned again that's the tension of it that squeezes between the two of them and i'm going to leave that alone i can't really get in there i don't want to disassemble too much let's get the wheel back on i'm going to take an air gun i'm going to blow the crap that's in around here too all right it's all set yeah i'm gonna go blow some of this crap out of here i got nowhere so unfortunately they broke coming out of there i don't know if i have any that's this tiny all the modern cars use them for like body panels and stuff let me go see i think they did on plastic for a reason i think there's a reason why there's no screws in that area let me go see if i can find something that's the smallest i have and that's not going to do it i don't think i'll try it but i think i'll have to wait till the stores open tomorrow to go get new ones we can still move the head though we can still uh just be very gingerly with with power because there's no support for that cable really i think it's what it's used for now it's stuck in there i'm committed now should be committed yeah that's not gonna do it yeah too big so i do want to put that crappy thing back in there to test it you have to be well i was looking at the other one these aluminum yeah that's aluminum wire good luck trying to run that on there and do my stash that's solid wire right [Music] hmm well unfortunately i think we're stuck working with this mess because this is all i have rusty wire that has unspooled itself and it's very brittle yeah i think what happened was when i went to go bend it over it literally just it snaps itself off and that's why it unspooled in the first place that's my excuse anyway so i can do my best to try to get this fed on and back through the gun and see what we get sometimes you can just close the door and it'll feed right around this one's got such a bend on it though going the wrong way and it wasn't happening i think i got it plus the fact that it's hollow when you cut it it has a tendency to flatten so the wire's not round anymore it doesn't want to feed through we got it in the jaws there i think we can back that tension off of here and um let's go straight in the wand out hit the trigger so you can get the feet all the way through so the wire has to feed at a certain rate to work well and right now it's all the way up i'm gonna go knock her down to about half speed turn the power on and there's two things that help with that one is the tension of this spring it it puts tension between the drive roller that's down below and it looks to me like it might not be in the might not be in the groove might not be on the yeah that roller has to come out a little bit i'm off the track i'm almost gonna be able to see it so what's happening is let me go turn it on i gotta get that screw face up again so that screw is not facing that screw's not facing the hole thank god for editing so that roller is not in the groove where it's catching the teeth on that it's proud of it let's go and bring that out a little right there there you go now it's lined up with it drop that down the tension feels a little heavy but let's just see what we get so we should get like an even feed rate out of it there we go that's more like it and the other part of that too sometimes this is too tight and it's causing it the spool just can't undo itself again this wire sucks too it's got rust and everything all over it so we're just trying to do the best what we can we're gonna go cut that off see how if you can see it flattened the end of the wire it'll be hard to feed and we're gonna go put a new tip on it because it came with some and let's see how we do uh right now it's on a which is the lowest output here's my it's the lowest output and you got to kind of adjust the wire feed speed that match how much heat you put in it more heat that you're putting in it more more power the more wire it uses so we're gonna probably have to try to go match that let's go i don't know two and a half see how that does for us see we get [Music] the piece of metal is way too big for what i'm doing but again we're just trying to try to weld that that's a little too high [Music] you could hear it you listen into it here i was popping before it was pushed the wire was so much wire was coming out was pushing the the gun off the metal it wasn't enough to go with it let's go turn up to b all right let's go to c [Music] [Applause] oh yeah [Music] actually works pretty good let me give her some more wire let's overdo it and i can hear that that that was too much you could hear where it was pushing the wire off of again i don't know about about three two four a and three all the way up i think it actually worked out pretty good the thing with flux core you're not going to get it pretty well you're not going to get it like you would with a regular mig with the gas it's just a dirty weld one thing that's kind of good about it though is that wind doesn't affect it so if you're in a windy climate like you turn a weld outside it will do halfway decent plus it splatters a lot too you see all the crap that is on there so i think that was uh a b c and d pretty much with all the same power setting and you can see as it's getting so hot is that you're actually able to kind of burn through it if you hit it with a wire wheel that that slag will come off the top of it and then just uh screwing around with the top setting uh running a little too much you can see where it was all puddling up and then knocked it back down again for the for the other one you guys are going to pick how many form i was it gives you a better idea what you can kind of go see i think we're on a again it's just not not enough power for the amount of metal that we're trying to go moving it's just sitting on top and globbing b and c i'd say you're kind of in between those two this is where i was saying that if you have a welder that is adjustable all the way you know there's no set levels of power that it's putting out so say it's we'll just make up numbers it's irrelevant but say uh uh 30 amps 40 amps 70 amps 80 amps are the settings that are on it well if you need to be you know like 37 is that the number that you dial in and you're between like say 30 and 50 or your two options you're just not close enough to kind of get really a really good weld ah of course this isn't this isn't prepped i didn't clean this piece of metal up it's a got crap all over it might be a piece of stainless i'm not sure and you know it's not hasn't been prepped and the wire has a ton of rust on us and either one of those is helping here the excuses anyway it's more about the welder right it seems like it's recovered pretty good and uh it should be back to functioning as a machine gun plus it's nice it's 110 you can kind of bring it wherever you want and and use it to on regular household current actually it performs better than i thought it would again the one that i had which was like the same output it was it was under 100 all the way up and it would barely weld you it made you a good welder because it was such a piece of crap okay so i'm gonna go pop those covers back on i think we're good to go on this i don't see anything that is uh outstanding we do need to reconnect that back again and we're gonna make it factory so we have the right tape that they used and then we'll go pop those covers back on yeah that was a piece of stainless magnet doesn't stick to it this roll of tape is probably 10 years old it does not want to peel apart and i'll show you a trick when that happens works works on most tapes i'll show you [Music] [Music] just want to get it where it's kind of warm to hot to the touch and what happens is you actually see it right there it will loosen the glue up again it re-solidifies the glue and uh allows it to to be taped again works really good for masking tape probably got one strain that got left behind from the beginning i gotta go cut that get that to go get it caught up with the rest of it and then it'll it'll do it so i'm gonna go get a blade factory repair like it never happened well this all back together grab a piece of steel and cleaned up the uh slag that was on it hot rolled just go try to dial in too much [Music] [Music] that sounds pretty good [Music] so [Music] not bad [Music] can we using that dirty wire too so a little bit of kickback when i first started but in a little sunk if i go for a little bit more power again this is probably about the max this welder can do let's try it one more time that's all the way up as far as power and that's what you're going to get out of flux core like i said is it's not a pretty well but it will do you know a fairly strong well again for crappy areas and uh if you're in the weather and all and it's also cheap because you know all you use is flux core lighting sucks so the weld all right guys well that worked out pretty good huh all we need is uh the two little plastic pieces for the support on the gun and i'll chase them probably tomorrow and get those in there but the rest of it seems to get popped back pretty good yeah i don't know how long it's sad my guess is probably 20 years it's just a gas but how long does it take for plastic to how long does it like for plastic to rust the plastic never quite seen that before but it definitely kind of corroded itself up to the point where it just wouldn't turn i don't know if when somebody grabbed it and went to go plug it in they heard that that cigarette pack plastic around the fan sounding like an electrical zapping going on as i i thought it was maybe at that point they just said ah you know i don't want to touch this thing it's deadly and they threw it to the curb but it came back pretty good in just uh about 45 minutes we played with it and uh we're able to resuscitate it actually well's pretty good too for the size that it is compared to the the crappy welder that i bought when this thing was probably around that same time frame you know 87 around there that solar which was you know sold through sears that thing was a piece of crap i i welded a lot of stuff with it i put my my plymouth satellites together quarter panels and everything frame was all done with that but again it didn't even have this it just had high and low and then i think for the speed it had a variable speed but it was just high and low for the output didn't have these four that were on there and i think it was rated about the same too about 88 seem to remember um usually stuff especially in the transformer realm i think on 120 volt around back then anyway 100 was about all you can kind of get out of them i think the new inverter ones go up higher on 110 again i'm not quite sure of that but this actually was quite nice for flux core welder again to convert it over to make it a mig welder it just would be you know cost prohibitive with the the price of new welders that are out there now but uh this will work fine for just what it i guess i is say i got nothing else left to to pick away at hit it with a dust rag maybe and that's about it he's a she's a winner not bad not bad happy with that hi guys thanks for hanging out with me i really appreciate it and we'll do it again sometime all right let's see what we get a little bit test piece on there we've got turned on a right now it should be the lowest power and each one i'll have to probably adjust the wire feed as you draw more power you have to kind of match the speed of the wire the amount of wire with the amount of welding you're doing i think it's on five right now sounds kind of high let's go knock it down about about two and a half [Music] i don't have a chip yet can't play without your tip
