Stainless Steel Tig Welding.

admin

I know for welding aluminum its for every .001 thousands use 1 amp is there a rule for running stainless?

Reply:Rule # 2...Never but never ever take your filler out of the argon zone...,zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:A very good rule zap I never knew that. I should have been more clear. What I ment is there a rule for amps on stainless steel like there is for aluminum?.
Reply:I can tell you that for .065 wall 304 tubing the DRO on my invertor reads 38- 42 amps most of the time when welding saddle joints.I find it best to go by the way the puddle looks and ignore the numbers. I have one of the Miller calculators but don't use it anymore, the numbers it gives are always much too high for my particular machine.I believe there is or was a welding instructor on this forum. He doesn't allow students to look at amp settings while learning tig. In this way they have to learn to read the puddle and not rely on some numeric idea of where the amperage should be. I think this is wise on his part.  In this way  people quickly to learn how to control things via the pedal, much like learning a foreign langauge by inserting oneself into a community that only speaks that language, rather than using a guide book and constantly translating. If that makes any sense.Glen
Reply:45 to 50 amps on .0625 304 dairy tube, this depends on the machine as well as they dont all read the same. this was what I used without walking the cup on a 100% penetration purged weld on 2" tube.This is a good starting point, I always read the puddle though like the above post states.mike sr
