Pure tungsten electrode, also known as wolfram electrode.

It can be manufactured with black surface, polished surface or ground surface.

It is normally marked with green.

This kind of tungsten electrode is firstly used when welding argon arc.

But under DC welding condition, the electrode can't prone to arc and may maintain unstable situation.

In these circumstances, adding rare earth oxide can greatly improve the situation.

Pure tungsten electrodes can work as welding electrode under ac condition or as resistance welding electrode.

Pure tungsten electrodes (AWS classification EWP) contain 99.50% tungsten and are typically less expensive than "alloyed" counterparts.


Performance

 

1. Pure tungsten electrode provides great arc stability for AC welding with balanced wave.

It also provides good arc stability for AC sine wave welding, especially on aluminum, magnesium, their alloy and stainless steel.

2. This electrode has superior features of small steam pressure, low resistance, good electrical conductivity and small thermal expansion and high elastic modulus.
