Welding Tips and Tricks

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?

Try these online welding calculators from miller. http://www.millerwelds.com/resources/calculators/

They help get a guy in the ballpark for amps.

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.
