welding auto sheet metal

[grumpyvette]

a good quality 130-140 amp MIG is almost ideal for body sheet metal welding jobs,its a darn good choice if your unlikely to use it on much more than auto sheet steel, and rarely over about 3/16" thick metal
much superior to the cheap flux core wire welders I see a few guys using.

Ive used a friends lincoln mig several times on body sheet metal at his shop with good results, but remember as you turn the amps up the duty cycle goes down and the cool down time between welding sessions increases

keep in mind shield gas and wire selection,
surface prep, plus experience,
all effect the weld quality,
and the larger amp migs can generally do the jobs that the lower amp rated migs can do, while the larger amp migs can also do the thicker stuff that out of the lower amp migs effective range, one other difference is DUTY CYCLE, the larger amp rated migs can be used almost constantly at the lower amp settings without over-heating or needing cool down time, something not generally true in the lower amp range migs
