I am looking at getting some gas to practice my TIG skills. I noticed that there are various Ar/He mixes available on top of just Ar. Quoting the sales brochure there are apparently quite a few benefits to Ar/He mixes like increased head transmitted to the weld pool, increased wetting, travel speed and optimized shape of penetration. Is anyone using Ar/He over here ? I am looking at general carbon steel, a bit of ss and maybe al when I get a chance, all thin stuff, mostly gauge thickness'. Should I bother with Ar/He or should I just get Ar ?
Reply:Just use straight argon. Adding Helium can help in some cases where your machine needs just a bit more power than it has for a specific job. However it's not going to turn a 165 amp class machine into a 250 amp class unit. You might gain 15-20 amps worth of output.If all you are doing is thin stuff adding helium to the mix will just increase your cost..No government ever voluntarily reduces itself in size.

Reply:Like DSW said, you need a particular reason so use helium. It is typically used to aid the welding of heavy alum. Argon will be just fine for steel.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea. |
