2% Thoriated Tungsten Electrode 1/8" x 7", Red, 10 Piece

TIG welding electrodes usually contain small quantities of metallic oxides, which can offer the following benefits: Facilitate arc starting Increase arc stability Improve current carrying capacity of the electrode Reduce the risk of weld contamination Increase electrode lifeRadioactive. Best for use in Direct Current (D/C) applications using transformer based constant current power sources. Best for use on non corroding steels, titanium alloys, nickel alloys, copper alloys. Good D/C arc starts and stability, medium erosion rate, medium amperage range, medium tendency to spit. (121488)
