【SIZE】: Diam 1.6 mm × L 175 mm, TIG Tungsten Electrodes with 1.5% Lanthanum 【NO RADIOACTIVITY】: Lanthanum tungsten electrode is a non-radioactive material 【APPLICATION】: This WL electrode also maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or the AC from square wave power sources 【PERFORMANCE】:Compared to pure tungsten, the addition of 1.5% lanthanated increases the maximum carrying capacity by approximately 50% for a given size electrode 【FEATURES】:Compared with thoriated tungsten electrodes, WL15 electrode has better arc performance and resistance to burnout.Another advantage is that the durable current is high but the burn-in rate is very small., Weight: 0.440924524 Pounds, Manufacturer: TEN-HIGH
