Me and my dad have been looking at getting a welder, but whats the difference between MIG, ARC and TIG welders? From what i can make out, is it something like MIG use gas, ARC use Electricity??

What should we be looking for in a welder or does it depend mainly on the aplication??

Try and get a Gas one as the Electricity ones drunk juice like anything. A Gas one will be a bit more portable too.

I don't know anything about welders really but my Dad had a cheap £90 jobby Electricity one which was shite so he lent a Gas one off his mate which was boss. He made a trailer with it within one day. It took him longer to take a Mini apart for the wheels and a few other bits he wanted for the trailer.

They all use electricity. MMA - Manual Metal Arc uses electrodes, which you have to chip off after welding. MIG - Metal Inert Gas uses gas and wire. TIG - Tungston Inert Gas is like a combination of the two were you use a rod and gas.

Get one with differant wire feed setting etc. Ones with high and low are crap, as are gasless setups.

Are there times when you would use a MIG welder instead of ARC welder and vice versa?

Right if your going to be welding on a corsa, you want either a MIG or Oxy-acetylene welder.

MIG runs off electricity and uses gas(argonshield light) to stop the weld from being exposed to atmospheric conditions. A lot quicker to weld with due to the heat being produced with electricity and not gas. Easier to learn with then gas welders.

Oxy-acetylene is a gas welder setup, two bottles, oxygen and acetylene. Very slow to weld with, produce a lot of distortion on flat panels if not corrected. Harder to learn then MIG.

Spot welders (resistance) are useful if your doing a lot of panel replacement, but just do a mig plug if your not using it constantly.

TIG welders primarily used to weld ally, are incredably difficult to learn to use. I've been learning for two years and still fcuk it up! Wouldnt bother with this unless your weorking on racing cars etc...

Hope that helps, if your going to be welding on your car, get some tuition from somebody that really knows what their doing. Colleges probably offer night classes for intro to welding plus it would help immensly. Welding your car can be fooking dangerous if you dont do it properly.

Good luck fella

i have a lovely little MigMate105 always works properly and don't use shitloads of gas, not that ideal for big welding jobs, but it's ok for bodyshells etc

Cheers everyone, looks like MIG is the way to go for me then

My dad wants to get one as he's just stripped his old 205 down and got the engine out of it which is mint condition, and he wants to make a trike (midlife crisis!)

I 'm wanting to use it to simply weld a few bolts upside down on the inside of my boot to secure a false floor in properly, so nothing thats going to be dangerous if i fuck it up

cheers again for the help fellas

Get a MIG welder, they are the easiest to use once you are practiced up. They are cheap too, and they are good for welding car parts up. Used mine to make my rear seat sub frames, and I'm going to be fabricating an exhaust system for my car with it.

Once you get really good, you can make aluminium stuff like header tanks cos they can weld aluminium up too
