hey was over at a old timers welding shop neat trick to lower amps on mig welder . he has a mig old miller mig and he figured out a way to lower amps for welding thin stuff . he told me it was a old welders trick he learned just with a piece of stainless steel welding rod . just don't touch wire after welding lol.

Cool tip. I'll have to remember that. I bet an adjustable carbon pile from an old battery tester would work great for that, too.Quote:

Yeah, that's a pretty cool tip. Adds a bit of resistance to the circuit(?)Quote:

just mic it it .125 thickness rod . what i est only need like 12 inches long since when i put my ground clamp at the very way to low on amps . dont touch the welding rod gets hot lol
I suppose if somebody was into the maths, he could calculate the resistance for a particular rod and get some semblance of accuracy.Quote:
