I'm working in a production facility that makes automotive part. Tig, 409 stainless,Miller machine, 12 cup w/gas lense. I'm trying to figure out how to reduce my burn through(graying). Due to the speed needs for production there's no time to put an argon backing on each piece. Im Putting brackets on 12-16 gauge tubing. Its proving to be a pain in the neck. When i run low amps it takes to long to puddle up and i burn through when i run high amps it almost immediately burns through.I tried setting my machine at 60 all the way up to 140. I'm doing decent but as I come off the bracket to join the puddle to the tube I always get a little Grey hot spot on the inside wall of the tube. Any suggestions?
