Lincoln Electric Part # KP4721-020

• Improved Arc Performance – Premium, consistent chemical composition to provide exceptional arc starts and re-starts while preventing arc wander.
• Minimized Oxide Build-Up – Oxide build-up on competitive tungsten electrodes creates burrs on the end of the rod, which can lead to an unstable arc. Our Tungsten Electrodes minimize oxide build-up, resulting in less time grinding, improving performance and productivity.
• Amperage Range: Performs best at medium to high amperages
• Current: Consistent DC & AC performance
• Performance Over Time: Great long term performance due to resistance from grain growth and contamination

Typical operating procedures for .020 diameter tungsten are 2 -20 Amps (DC-), 2 -15 Amps (AC 50/50 Balance), 2 -15 Amps (AC +70/-30 Balance). 2% Lanthanated EWLa-2 performs best at medium to high amperages. Has consistent DC and AC performance. Offers great long term performance due to resistance from grain growth and contamination. Sold in a pack of 10.
