My Miller Syncrowave TIG 500 machine will weld up to 650 Amps, My smallest MIG welder Hobart 140 amp machine with .023" wire is all I mainly use for sheet metal . A damp rag is useful to keep things moving and under control. I assume we are not comparing flux core Mig to TIG, correct, which is not what i would use no matter what.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
