Blue Demon 5/32" EWP Pure Tungsten 7" Electrodes (10-Pack)

5/32" EWP Pure Tungsten 7" Welding Electrodes (10-Pack)

Sold in 10-packs, 5/32" Blue Demon EWP is a PURE unalloyed tungsten electrode (99.5%tungsten minimum) that is non-radioactive. Its current-carrying capacity is lower than that of other tungsten electrodes.

EWP provides good stability when used with AC, either balanced wave or continuously high frequency stabilized. It can be used with DC and also with either Ar or He (or a combination of both) as a shielding gas. Blue Demon EWP Pure Tungsten Electrodes maintain a clean, balled end, which is preferred for aluminum and magnesium welding.

Blue Demon EWP electrodes have reasonably good resistance to contamination of the weld metal by the electrode, although oxide containing electrodes are superior in this respect. EWP is generally used on less critical applications, except for welding Al and Mg. The lower cost EWP electrodes can be used for less critical applications, however, where some tungsten contamination of welds is acceptable.
