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 carryin g 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 Show more
