Learning to mig weld
When you’re learning to mig weld you’re going to need to cover a few basic steps first, and they are:
- Welding safety
- Preparation
- Machine set up
- Installing mig wire
- Tack welds
- Torch postion
Like anything, safety is paramount. You should always wear thick and heavy clothing such as overalls, a good strong pair of leather boots (preferably steel capped boots), welding gloves and a welding helmet.
When you mig weld the arc gives off ultraviolent and infrared light. This light is very damaging to your eyes and because of that you need to be protected from it with a welding helmet.
Not only is the welding arc bad for your eyes but it is very hot, so it’s a good idea to use a quality pair of leather welding gloves. The best ones that I have come across have been the ones that are Kevlar stitched. And by the way, the day that you don’t put on your gloves will be the day that you pick up that hot bit of metal that you just welded and forgot about. Been there before.
Once you’re all geared up and ready to mig weld you need to prepare the surfaces. Any traces of oil, paint, grease or heavy rust will have to be grinded off back to shiny metal. This is very important in making a good weld bead.
The welding wire will need to be installed onto the machine and the correct size contact tip will need to be fitted, make sure that your welding nozzle is clean. Also check that you’re using the correct size feed rollers for the wire.
Depending on the thickness of metal that you’re going to weld you’re either going to need more power or less power. This will be a matter of trial and error. Once you have this sorted you’re going to make some tack welds first.
A tack weld is a small weld that is used to hold all the larger pieces of metal together. You tack weld first so that you can check that all the parts are in the right places and everything is aligned and square.
Now once it is all tacked up and ready to go you can fully mig weld it up. Finally when you’re learning to mig weld you need to be aware of your torch position. If you are using a flux cord wire you will need to use the pull technique, which is like when you are stick welding and you drag backwards. If you use a solid mig wire such as an ER70S-6 class wire with a shielding gas you can either push or pull. Learning which style suits you best will slowly take time.

Watch the video related to mig welding
This MIG Welding Video shows the demonstration of a push welding technique that is use when mig welding see here for more info on mig welding www.learn-how-to-weld.com When mig welding you can either push or pull the welding torch. The push technique is the most common. www.learn-how-to-we…
Help answer the question about mig welding
Can someone tell me about using argon for mig welding?What exactly does Argon do during mig welding? (such as the rocker panel my cousin is welding on my grandfather's truck)
Also, how much does it usually cost to rent/lease a small argon tank for a month in the New Hampshire/Mass area?

Ha Ha very funny willystylee.
Have you guys seen “You Can’t Weld This!”? It’s pretty funny… The guys over at WeldingMart com had it made! Do a youtube search for it
must i use welding gogles when seeing the video !!!! thxs???
Mig is the way to go when it comes to welding on body panels and exhaust systems.Its easyer to use and is better suited for thin metal.
Mig welding is a combination of speed of wire, correct wire, gas supply and right machine settings. If you have the gas and wire I suggest that you trial and error with speed and power setting. You must also make sure that you have a very good earth connection. It really is trial and error.
I have a Lincoln Power 140C MIG and have done many frames and a lot of bodywork with it. Some roll cages too. Works great. Also is 120V so just plug it in at home and go to town.
not much different….you wont have the slag that rod leaves…the application is mostly the same….you hold the nozzle at about the 45* like rod welding….I like either push or pull method…it takes a touch of practice but if you've had enough experience then you will fall into it very easily…I love it for filling large gaps or cracks…dont have to slag at all…just keep applying filler wire til it is filled. Overhead will take you a little time to get your hand and eye and settings….but, works like a charm……..good luck
Im beginer.When Im welding Icant see difference between push and pull, In structure of weld.But I have only cupple hours of welding on my account:) Thank you
yeah u need to, the even looking at an arc on a computer screen will burn your eyes. Better hurry and go get one from the idiot store
very nice video
rofl makes me feel so dumb
It should not take you very long at all since you are already certified as a TIG welder. Getting certified will require a certain number of hours training and taking a test of course, but you should not have any trouble doing it.
On your first try, you will probably lay a better bead than I ever did.
Doc
pull … deeper penetration …. push … less penetration.
pull … puts more heat into the weld puddle.
push … puts less heat into the weld puddle.
This isn’t always the case though … uphill & downhill are the exactly opposite. Uphill digs deeper where as downhill doesn’t.
When your practicing … don’t fill in you weld at the end … you can easily tell which methods penetrate deeper into the base metal.
Get a wire feed TIG machine for ease of use. 16 Gauge is not very thick and can easily be welded with a small machine.
join the military..plenty of hummves to learn on…or get a welder and weld..
