Tungsten Electrodes

CK-TUNGSTEN-ELECTRODES-BANNER

 

1.5% LANTHANATED (GOLD) EWLa-1.5/WU5

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 steel, titanium alloys, nickel alloys, copper alloys, Best D/C arc starts and stability, low erosion rate, wide amperage range, no spitting.


 

2% LANTHANATED (BLUE) EWLa-2/WL20

Principal Oxide: 1.8-2.2% Lanthanum Oxide

NON-RADIOACTIVE. Best general-purpose electrode for both Alternating 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, aluminium alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good arc starts and stability, medium to high amperage range, low erosion rate.

 

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 content 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: 0.7-0.9% Zirconium Oxide

NON-RADIOACTIVE. Best for use in alternative current (A/C) for aluminium alloys and magnesium alloys using inverter or transformer based constant current power sources. Balls, well, handles higher amperage than pure tungsten with less spitting, better arc starts and arc stability than pure tungsten.

 

2% CERIATED (GREY) (FORMERLY ORANGE) EWCe-2/WC20

Principal Oxide: 1.8-2.2% Cerium Oxide

NON-RADIOACTIVE. Best for use in Alternative 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 properties, long service life, excellent arc stability. Low erosion rate, best at low amperage range, no spitting, good D/C arc starts and stability.

 

LaYZr (CHARTREUSE) EWG

Principal Oxides: 1.5% Lanthanum, 0.08% Zirconium, 0.08% Yttrium Oxides

NON-RADIOACTIVE. Best for automated or robotic applications in Alternating Current (A/C) or Direct Current (D/C) due to low voltage tolerance (changes in tip to work piece distance) 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, Very stable tip geometry, runs cooler than 2% Thoriated with longer life, low to medium amperage range. Very best low amperage starts.
