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.
0.8%ZIRCONIATED [WHITE] EWZr-8/WZ8
Principal Oxide: 0.7-1.7% Lanthanum Oxide
NON-RADIOACTIVE.Best for use in Althernating Current [A/C] for alluminium alloys and magnesium alloys using inverter or transformer based constant current power sources. Balls well, handles higer amperage than pure tungsten with less spitting, better arc starts and arc stablitiy than pure tungsten.
1.5%LANTHANATED [GOLD] EWLa-1.5/WLI5
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 power sources. Best for non corroding steels, titanium alloys, nickels alloys, copper alloys. Best D/C arc starts and stability, low erosion rate, wide amperage range, no spitting.
2%CERIATED [GREY] [FORMERLY ORANGE] EWCe-2/WC20
Principal Oxide: 1.8-2.2% Cerium Oxide
NON-RADIOACTIVE.Best for use in Alternating Current [A/C] or Direct Current [D/C] applications using inverter or transformer based constant current power sources. Good for low-alloyed steels, non corroding steels, aluminium alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good ignition and re-ignition propperties, long service life, excellent arc stability. Low erosion rate, best at low amperage range, no spitting, good D/C arc starts and stability.
PURE [GREEN] EWP/WP
Pricipal Oxide: None
NON-RADIOACTIVE.Good for use in Alternating Current [A/C] for alluminium alloys and magnesium alloys in low to medium amperage applications using transformer based constant current power sources only. Balls easy, tends to spit at higer amperages. Used for non-critical welds only.
2%LANTHANATED [BLUE] EWLa-2/WL20
Principal Oxide: 1.8-2.2% Lanthanum Oxide
NON-RADIOACTIVE. Best general purpose electrode for both Alternanting Current [A/C] or Direct Current [D/C] using inverter or transformer based constant current power sources. Good for low-alloyed steels, non corroding steels, alluminium alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good arc starts and stability, medium to high amperage range, low erosion rate.
