EWTh-2 X 3/32 in Tungsten Electrode 10 Pack 2% Thoriated Blue Demon

Description

The higher thoria content in the EWTh-2
electrode causes the operating characteristic
improvements to be more pronounced than
in the lower thoria content EWTh-1. The
additional thoria also provides about 20
percent higher current-carrying capacity,
longer life and resistance to contamination
of the weld. Should it be desired to use these
electrodes for AC welding, then balling can
be accomplished by briefly, and carefully,
welding with DC electrode positive prior to
welding with AC. During AC welding, the
balled end does not melt and so emission is
not as good as from a liquid ball on an EWP
electrode. Note: If electrode grinding is used
special precautions relative to ventilation
should always be considered to avoid
ingestion of dust.
