Rare Earth (TURQUOISE) EWG (principle oxides: 1.5% Lanthanum, 0.08% Zirconium, 0.08% Yttrium oxides). Best for automated or robotic applications in Alternating Current (A/C) or Direct Current (D/C) due to low voltage tolerance (changes in top to work piece distance) using inverter or transformer based constant current power sources. Very stale tip geometry runs cooler than 2% Lanthanated with longer life, low to medium amperage range. Best low amp starts. Good for low alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys.
