Arc or Mig?

Spray transfer? On a car body/chassis? I think not.
pumba:
if a mig set isnt set up properly, wire speed, amps, volts penetration can become a problem, cold lapping etc,
gas, argo shield light is what we use in work all day long bottle after bottle, mig is a lot easier to use in the over head position,, eisier to miantain the right angles, perfect for welding vehicles,
for exsausts, thin plate, etc, tig has got to be the choice,
mma is good for most things, but i would use mig for vehicles, its quite a cold weld, not as much distortion compared with mma,
i gas welded my pick up because i cant afford a mig welder, now thats a pain to do, poping, blowing all kinds of crap back in your face

No problem on a chassis, and essential if you start welding up engine mounts, towbars and recovery points.
Xtremeteam:
