Trying to understand what is happening. I'm TIG welding mild steel frame from 2"x1"x1/8" tubing. All corners are cut at 45deg and are butt jointed. all 4 corners have been sanded from any mill scaling. 3 corners welded fine. on 1 corner i get all kinds of spatter. tungsten gets all red. loses grinded point in seconds. if feels as if gas is gone but plenty of argon in the bottle. pyrex cup got all the sputter metal on it, the screen became junk. i stopped, cleaned up, reground and replaced consumables but results were the same. after 3 different attempts i just stopped welding that corner. I dont understand whats happening...
