Pure Tungsten Electrode
Suitable for welding under alternating current
The tungsten electrode does not increase any rare earth,
the electron emission ability is smallest,
therefore it only suits to alternating current under the big load condition welding,
like aluminum and aluminum magnesium alloy welding and so on.
