application:2% Thoriated (Red) :WT20 thoriated tungsten electrode is usually used for DC welding of carbon steel, stainless steel, nickel alloy and titanium metal.
WL15 and WL20 lanthanum tungsten electrodes are very good for DC welding and AC welding, and have excellent performance.
WC20 tungsten-cerium electrode can easily start an arc with only a small current, and the arc-maintaining current is also small. Under low current DC conditions, cerium tungsten electrodes are very popular, especially for joining pipes and small parts, intermittent welding and specific number of welds.
WZ8 zirconium tungsten electrode is suitable for AC welding of magnesium, aluminum and its alloys.
