2% Lanthanated Tungsten Electrode 3/32" x 7", Blue, 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 lifeNon-Radioactive. Best general purpose electrode for both Alternating Current (A/C) or Direct Current (D/C) using inverter or transformer based constant current power sources. Good for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good arc starts and stability, medium to high amperage range, low erosion rate.
