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 and increase electrode life.

Best general purpose electrode at medium to higher amperage for both A/C or 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 and copper alloys.

  • 2% lanthanated
  • Diameter of 3/32"
  • Electrode length of 7"
  • Blue tipped
  • AC or DC operating
  • Non-radioactive
  • Oxides used are primarily zirconium, thorium, lanthanum or cerium
  • Additions are 1% - 4%, improve arc initiation, especially when direct current (DC) welding is employed
  • Thorium oxide (thoria), effective in terms of long life and thermal efficiency
  • Zirconium oxide (zirconia) has been commonly used for alternating (AC) TIG welding, welding aluminum
