stainless steel a/c

admin

I have a need to weld 1/4" thick 316 S.S.. The SS box contains magnets, magnets affect D.C.   I would like to use the syncro 350 on AC. any tips, ideas, tung recommendations?Thanks, Tim.Tim Beeker.
Reply:I don't know about the welding, but A/C may weaken the magnets . . . . heat wont do them any good either . . .-- fredLincoln 180C MIG
Reply:Thank you for the response.They are rare earth,Heat will not each them, hopefully the ac will not affect them much either.Tim Beeker.
Reply:GTAW AC requires zirconiated tungsten. I think ceriated would also work. Would not advise GTAW AC on SS though, perhaps consider SMAW AC. Give GTAW DC a go on the 316 in the vicinity of the magnets, it may work.

Reply:Hey DesertThat may work at the lower end of the current range, however for arc stabilty, current carrying ability and lower risk of weld contamination, zirconiated is a better choice for AC. Thoriated will struggle to cope with the AC positive half cycle.Cheers
