Product description： WT20 Red Thoriated Tungsten Electrode Easy to get up the arc, in the welding process unceasingly arches. The electric arc is stable, not spread around and disperse the arc. The electricity saving effect is obvious,gets up the arc current relatively Drops 20 - 50%. Because welding current lower,in the useprocess is not easy to appear splashes,extremely not instable circle. The electrode causes Is long with the life. The thorium tungsten electrode is thetraditional electrode,has the superior welding performance,but the tungsten thorium electrode slight radioactivity,caused it the application to receive certain resisting and the limit. List Included: 10 pieces tungsten electrode 1.0mmx150mm 1.6mmx150mm 2.0mmx150mm 2.4mmx150mm 3.2mmx150mm Item Package Quantity: 10 pieces NB: Due to the consumable parts compatible ability are limited, please MUST confirm the Ref code is matched.
