2% Thoriated(red)eWTh-2/WT20Principal Oxide:1.7– 2.2% Thorium OxideRadioactive.Best for use in direct current (d/c) applications using transformer based constant currentpower sources. Best for use on non corroding steels, titanium alloys, nickel alloys, copper alloys. Good d/carc starts and stability, medium erosion rate, medium amperage range, medium tendency to spit.1.5% Lanthanated(GoLd)eWLa-1.5/WL15Principal Oxide:1.3 –1.7% Lanthanum OxideNoN-Radioactive.Best for use in direct current (d/c) as an alternative to 2%thoriated using inverter ortransformer based constant current power sources. Best for non corroding steels, titanium alloys, nickelalloys, copper alloys. Best d/c arc starts and stability, low erosion rate, wide amperage range, no spitting.
