Pure Tungsten Electrode 5/32" x 7", Green, 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. Good for use in Alternating Current (A/C) for aluminum alloys and magnesium alloys in low to medium amperage applications using transformer based constant current power sources only. Balls easy, tends to spit at higher amperages. Used for non-critical welds only.
