I'm wondering also, if I should do less amps and 2 passes, or high amps and 1 pass. I will really only be welding turbo manifolds.

 

quick bump before I go off to bed.

 

130 amps (obviously i dont floor the pedal) at the power source. When welding stainless, you need to get it hot really fast, and go like hell when you weld it. Otherwise you will burn the carbide up back into the chromium and stuff. No really its true. If you go slow you will bet a lot of sugaring, and your weld zone will loook like ****. No color = bad. You want it to burst with color when its done.

Here is some that i've done
the top side bead that you see is me going hot and fast, the other side you can see the back has sugaring. My instructor told me to go slow, with low amps. And you see what happened.


Notice the heat effected zone. Think of welding stainless as boiling a pot of water. Lower amps doesn't mean you won't burn up the metal. It just takes longer to get it hot, and by the time you have gotten hot enough to weld, your h.e.z. is out of whack, and the rest of your weld will be too hot to maintain good color and still retain good stainless characteristics. Weld hot and fast.

 

still looks alittle hot...

usually 80-100 amps for me and im never full pedal..

 

I usually just have the dial on 180 and run off the pedal.

 

Hrmm, it seems like everyones different then. Another person told me they run about 135.

I'll just play around with it, and do what looks the best...

 

It also depends if you are gapping the pipe.

I agree. Those welds were from a long time ago, and they are barely within color.
