A lot depends on the electrode size......1/8" or 3/16".....and material......60105P (red wire), 7018 LH, 7024 (jet wire) and the thickness of the base netal....which amperage is used......the cheap welders usually don't have any current limiting or current smoothing capabilities and the weld appearance is sort of shaggy or un even. MIG is OK, TIG is best (with the correct filler metal) easy to control, both need a shield gas 75/25 argon/ CO2 mix......just my opinion......Im getting ready to weld the brackets for a buddy seat in
my 65 Coronet. I bought a cheapo arc welder "arcCaptain 130".
I was curious if anyone might know a general amperage to use...floorpan is pretty thin.
Thanks in advance !!!
