1.5% Lanthanated Tungsten Electrode 1/8" x 7", Gold, 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 for use in Direct Current (D/C) as an alternative to 2% Thoriated using inverter or transformer based constant current power sources. Best for non corroding steels, titanium alloys, nickel alloys, copper alloys. Best D/C arc starts and stability, low erosion rate, wide amperage range, no spitting.
