Tungsten Electrode Contamination:


As the rod (TIG filler) touches the electrode (tungsten) contamination occurs. See the weld that is contominated in this video clip because you'll see that you'll need to take a half inch of the tungsten off and begin your welding again. (Duration: 1 min. 45 sec.)

Video Clip is from Tig Welding Basics produced by Ron Covell, Welding and Metalworking Instructor.
