Walking the Cup vs TIG Finger for Vertical Tee Joint Welding

Learn essential TIG welding techniques for vertical tee joints through a detailed comparison of walking the cup versus using a TIG finger. Master the 3F vertical tee joint welding process commonly taught in welding schools, which serves as valuable training for socket welds. Discover proper welding parameters including 140 amps settings, 3/32" ER70S-2 filler rod usage, and optimal gas flow setup with a #6 gas lens cup at 15-20 CFH argon flow rate. Explore situations where walking the cup may not be feasible and understand how a TIG finger can help maintain focus on weld quality while preventing finger burns during challenging positions.
