A versatile, high penetrating tubular wire. Excel-Arc is designed to be used with a 100% CO2 or a 75% Ar/25% CO2 gas mixture to make fabrication easier in any position. You'll see a low-hydrogen weld deposit in a spray-type transfer of weld metal, with less smoke, deep penetration, and a high deposition rate. With low spatter, clean up is a snap and it's great for single or multi-pass jobs. Exceeds AWS requirement of 20 ft. lb. at both 0 & -20 degrees Farenheit.
