EWP 3/32 Tungsten Electrodes Blue Demon 10 pack

Description

EWP (Pure) are unalloyed tungsten electrodes
(99.5% tungsten minimum) and are nonradioactive.
Their current-carrying capacity
is lower than those of other tungsten
electrodes. They provide good stability
when used with AC, either balanced wave
or continuously high frequency stabilized.
They may be used with DC and also with
either Ar or He, or a combination of both,
as a shielding gas. They maintain a clean,
balled end, which is preferred for aluminum
and magnesium welding. These electrodes
have reasonably good resistance to
contamination of the weld metal by the
electrode, although the oxide containing
electrodes are superior in this respect. EWP
electrodes are generally used on less critical
applications, except for welding Al and Mg.
The lower cost EWP electrodes can be used
for less critical applications where some
tungsten contamination of welds is acceptable.
