Tack welding with a TIG

admin

Do any of you guys do this? Starts at 2:02 in the video. I noticed he touches the tungsten on the metal, does a split second weld to tack, then pries the tungsten off the metal.
Reply:I don't think he is touching the tungsten to the metal. See the recessed tungsten? He is just rocking the cup forward then backward to see the tack. I do the same on occasion.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.
