Lanthanum tungsten electrode(WL15)

Lanthanum-tungsten electrode contains 0.8%-2.2% Lanthanum trioxide,which is easy to arc at low current. Mainly used for direct current welding.It also performs well in AC welding.

Tungsten composite electrode (WES)

Composite tungsten electrode, also known as ternary composite tungsten electrode, it is easy to start and repeat the arc, and the life is longer in the case of large welding cycle, due to the three kinds of oxides are involved in the electrode
