Strong practicality and heat-resistant tungsten electrode

It is in possession of  material with high-melting, high density, anti-corrosion, good conductivity of heat and electricity, which is fixed by tungsten clamp and back cap in the torch. Normally, the diameters (2.4mm——8.0mm) are applied.

In main arc, it means for cathode, work piece does for anode, In pilot arc, it means for cathode, nozzle does for anode. When you put on or take off it, please make sure the pilot is off.

Generally, it is proper to retreat （2-4mm）into nozzle as putting on, which is available to tungsten calibrator.

Please grind the tungsten electrode when the arc stream is disperse.

It should be central and the angle should be 22 °as grinding to avoid a short circuit. 

It appears disparate colour through grinding and polishing, which means the tungsten content is different. The launch efficiency of pure tungsten is very low and it would form crystallization in the high temperature to make the tungsten wire break. In order to overcome these characteristics, the rare earth element is add to it, which It can not only increase the recrystallization temperature, but also activate electron emission.
