<strong>Try and get the most powerfull mig you can, as you can always turn the power down for thin metal but once its maxxed out you can't do anything about it, about 150amp is suitable for most jobs upto about 6mm thick (quater plate - frame wrap ?)
work out where you'll be doing most of your work, if you'll be using outside in the open try and get a 'gasless' mig, their not actually gas less, the gas is in the mig wire so it doesn't get blown away from the work area by wind etc. If you'll be using it inside a garage then a standard mig with a gas bottle will be fine, although gasless is less hassle.
The gas creates a shroud of carbon dioxide around the work area which works as a FLUX, gass less migs have the flux in the wire (different wire for both types)
start by welding together any old scraps of metal you have lying around, practice makes perfect.
The mig should be set up so that it sounds like bacon sizzling when you're welding, you'll need to adjust the speed of the wire feed and the amount of power to get it just right.
Never try to weld dirty metal, it sucks and you'll get burnt.</strong><hr></blockquote>
its suppose to sound like frying eggs
get it right j/p jon
dont weld painted surfaces either or u will be sick for days!!! i prefer arc to mig
