CK Worldwide is a leading brand in the TIG welding world. Their Tungsten is very popular amongst welders and a few of them are our best sellers on the website. Read below to learn about each color and see which one is right for you.
2% THORIATED (RED) EWTh-2/WT20
2% Thoriated is ideal for Direct Current (D/C) applications with transformer-based constant current power sources. Optimal for non-corroding steels, titanium alloys, nickel alloys, and copper alloys. Offers reliable D/C arc starts and stability, moderate erosion rate, amperage range, and tendency to spit. This material is radioactive.
0.8% ZIRCONIATED (WHITE) EWZr-8/WZ8
Zirconiated is Non-Radioactive. Suited for AC use on aluminum and magnesium alloys with inverter or transformer-based constant current power sources. Offers improved handling of higher amperage, reduced pitting, and superior arc starts and stability compared to pure tungsten.
1.5% LANTHANATED (GOLD) EWLa-1.5/WL15
1.5% Lanthanted is Non-Radioactive. Suited for Direct Current (D/C) as an alternative to 2% Thoriated using inverter or transformer based constant current power sources. Ideal for non corroding steels, titanium alloys, nickel alloys, copper alloys. Best D/C arc starts and stability, low erosion rate, wide amperage range, no spitting.
2% CERIATED (GRAY) EWCe-2/WC20
2% Ceriated is Non-Radioactive. Ideal 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, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Consistent 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.
PURE (GREEN) EWP/WP
Pure tungsten is NON-RADIOACTIVE. Ideal for use in Alternating Current (A/C) for aluminum alloys and magnesium alloys in low to medium amperage applications using transformer based constant current power sources only. Balls easy, tends to spit at higher amperages. Used for non-critical welds only.
2% LANTHANATED (BLUE) EWLa-2/WL20
2% Lanthanated is 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. Ideal for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good arc starts and stability, medium to high amperage range, low erosion rate.
LaYZr (CHARTREUSE) EWG
Layzr tungsten 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, aluminum 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. The best low amperage starts.
