2% Thoriated
(red)
eWTh-2/WT20
Principal Oxide:
1.7– 2.2% Thorium Oxide
Radioactive.
Best for use in direct current (d/c) applications using transformer based constant current
power sources. Best for use on non corroding steels, titanium alloys, nickel alloys, copper alloys. Good d/c
arc starts and stability, medium erosion rate, medium amperage range, medium tendency to spit.
 
1.5% Lanthanated
(GoLd)
eWLa-1.5/WL15
Principal Oxide:
1.3 –1.7% Lanthanum Oxide
NoN-Radioactive.
Best for use in direct current (d/c) as an alternative to 2%
thoriated using inverter or
transformer based constant current power sources. Best for non corroding steels, titanium alloys, nickel
alloys, copper al
