I understand that for mild steel 1 amp is needed for every .001" (thousandth of an inch). I read on here stainless steel needs 2/3rd's of an amp every .001".

What I do not know is, what's the guideline for aluminum? How many amps for every thousandth of an inch is necessary to weld it out?

For aluminum I generally just add 25 amps to steel requirements, so for .125 aluminum I'd set at 150. Stainless I just set at steel levels. When I'm lazy ill just set the machine on max and use the pedal.
