Tungsten Electrode WT20 is America's favorite electrode for a reason. Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications.
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 electrode causes are long with the life. The thorium tungsten electrode is the traditional electrode, has the superior welding performance, but the tungsten thorium electrode slight radioactivity, caused it the application to receive certain resisting and the limit.
