MIG Welding Basics - Do’s and Don’ts

what's going on guys Mike here we're back with another video now we're going to take it back to the basics of mig welding we're gonna do our dues and our don'ts here today I'm going to show you how to make sure you have the right dry rolls how to make sure you at jawar wire speeds correct and what happens when it's not correct I let's get to it [Music] alright guys like I said we're gonna check out our machine before we start welding make sure you turn your wire feeder off turn your machine off now what we're going to do is we wanna make sure our drive rows are the correct size for our MIG wire we're using oh three five Maguire so to check that what we're gonna do we're open up to the side to expose the dryer rolls we will take the tensioner off we're gonna lift it up to remove the drive row we're gonna make sure it says old three five for the MIG wire make sure all of them are all matching and correct when they are go ahead and place it back on there make sure it's locked into place see how the from that lock you can always check it make sure they're locked in place see that lock them in place tensioner down turn on your machine now we're ready to weld now let's get to it good I wasn't ready for it good alright guys so we're gonna get into the video now now I'm gonna show you what's gonna happen whenever you don't have the right amperage or voltage and I'm gonna show you what happens when you have the wrong wire speed as well and I also want to give a shout out to outlaw leather for hooking me up with the new world to hood courtesy to them now let's break this baby in let's get some world and done alright guys so this right here is gonna be an example of what low-voltage but the correct wire speeds gonna look like and gonna sound like as well because with me you could tell by the sound as well so let's get to it now do you see how it's yes flattery doesn't want to move in a very good connection now that guy's is because my voltage is too low okay now we're gonna turn the voltage up to high and turn the wire speed down to show you correct voltage but not enough wire speed so on that first one I was at 15 volts and about 2/10 wire speed so that my wire speed was correct but my votes was incorrect now I put my volts at 19 volts which is correct and I put my wire speed about 125 130 now let me show you what happens when it's too hot with not enough wire behind it if you have the best one they connected smooth that's real flattery you don't want to hear that when you're ready that's what happens when you have wrong wire speed and wrong voltage and correct wire speed and correct incorrect voltage all right now I'm gonna show you what happens whenever you don't have the correct gas coverage so we are using 75 25 75 percent argon 25 percent carbon dioxide gas so I'm going to show you how I'm going to turn down the gas a little bit and go from there alright guys so I'm on the correct voltage and correct wire speed which is gonna be nineteen boats and about 220 on the wire speed now this is with no gas behind the MiG at all i turn the gas completely off so let's see what it looks like and what it's gonna do so that was correct wire speed and voltage but as y'all can see all it does is cause a lot of porosity it's real smoky and very unclear and very nasty sounding but you see how I just in is kind of like cratered in has a lot of wormholes for the porosity so nasty I left the plate in the background as well how dirty I made it is because there was no gas behind the wire now what we're gonna do is we're gonna turn the gas up a little bit and show you what not enough coverage is when I but you the gas is on alright so I had the correct wire speed and voltage down but less gas coverage the first one was completely off so I'm at 19 volts about 220 wire speed now and my CF H is gonna break about 15 okay let's see what it does [Music] alright guys so you see how the beat started up real nice but when they realized that there was enough of not enough of gas covered started creating this little pool of porosity right here that's because there's not enough of gas coming out of the nozzle to cover the puddle now enough with the don'ts and how not to weld now let's get to laying a nice pretty bead down and at the end I'm gonna show you how to stack down to it Meg let's get to it alright guys that's enough for the don'ts of Meg glory then let's get into the dues how to lay a proper bead on a 2 ft joint now the motion I'm gonna be using is gonna be I'm using seaguar by the way meg and TIG wire is the same thing it is er 70s 6 except the diameter is a little bit different that's all it is so with this Meg water on this fill it world the motion we'll be using to lay a nice flat bead to conjoin these two metals it's a simple start the top come out to the bottom and I'm gonna roll it around roll it around I go like a clockwise circle like that just so I know I'm hitting the bottom the top bottom top ok now I'm at 19 volts I'm at 220 wire speed and my cfh it's gonna be a brown 35 okay now let's get to some welding alright girls like I say I'm gonna do a clockwise circle [Music] either neither the barest nor you have then my pet is actually following the bastards nicely the Bears just put some big balls coming out back into the party alright guys so like I said with good voltage good wire speed and good gas coverage you're able to lay it down a nice clean flat bead connecting both walls so the metals can join together see how it got nice and clean got a little silicone there because remember it is kind of like TIG wire this is er 70s 6 so it's gonna have a little silicone left behind now let's wire will it up and see what it looks like alright guys well there you have it a nice smooth bead touching both walls nice and uniform at the correct voltage correct gas coverage and correct wire speed alright guys so like I said we're gonna try to stack some diamonds now we're on the same settings but what we're going to do is like when we use with our 60 tin rod you can whip out of the puddle and back into it to the leading edge or you can do the triangle motion like you would do it in a hot pass in order to lay it down flat so I'm go ahead and give it a shot [Music] alright guys so we go in a head stack sometimes as easy as you can see each little feather is at the leading edge of the one in front of it all stacked up all the way down alright guys this was helpful feel free to subscribe to us on YouTube follow us on Instagram and Facebook hope you have a good one thank you
