EWP (Pure) are unalloyed tungsten electrodes and are non-radioactive. EWP electrodes are generally used on less critical applications, except for welding Al and Mg.
- Current carrying capacity is lower than those of other tungsten electrodes.
- Provide good stability when used with AC, either balanced wave or continuously high frequency stabilized.
- May be used with DC and also with either Ar or He, or a combination of both as a shielding gas.
- Size: .040″ – 5/32″
