Is it possible to tig weld aluminum with a dc only miller xmt 304cc.Thanks
Reply:Yes just use helium for sheilding gas. Not to good for thin material though compared to AC but will work if thats what you got. We do it alot at work on very thick aluminum.Syncrowave 250Millermatic251Trailblazer302Thermal Dynamics cutmaster52
Reply:Thanks for the reply. I plan on welding 1/4" plate aluminum. All I have is Argon and Co2/argon mix bottles. I actually just bought the welder and I'm looking to learn how to tig weld with it. Should I just avoid using aluminum to learn?

Reply:I would try it out with steel first to get a handle on it if you haven't done any tig before.DC tig runs alot different then AC and will not look like most aluminium welds your used to looking at. It will tend to look dirty when welding leaving a black soot around the weld area that will brush off and it will penetrate alot easier than AC with argon and might take awhile to get the hang of if your new to it. The other downside to DC alum. is helium is big money right now,I think it cost me $98 last time to fill a "T" bottle 291 cubic feet I think last time and that was at a corporate rate,before that they hit me for $145.Syncrowave 250Millermatic251Trailblazer302Thermal Dynamics cutmaster52
Reply:I tried tig'ing aluminum on dc with argon before, what a disaster, in both dcen and dcep. AC with high freq works much better.
