Thread: Sst tig problem by newbie.

    Sst tig problem by newbie.

    wELDING SST INVESTMENT CASTING BELIEVED TO BE 316. TUBE CROSS SECTION 3" DIAM,WALL .15". 1/16 TUNGSTEN, 35 AMPS
    I start a fusion bead without full penetration and all is well. After 5 to 10 seconds, arc becomes intense and bright, unable to see to continue.
    Welded area is perfect. Restart and it goes well again. Any ideas? tungsten too hot?

    Probably not 316 , are you having the same issue when welding on carbon steel or any other base metal that is positively identified?
