• Excellent performance in flat and horizontal position with either 75%Ar-25%CO2 gas mixture or 100%CO2.
• Easy slag removal greatly reduces the cleaning time after welding.
• Due to less spattering and small spatter size, adhesion of spatter to the base metal is almost eliminated

Tables shown are approximate values that will vary depending on welding conditions(WESO, Cable length etc.). Voltages shown are for 100%CO2 shielding gas. For 75%Ar-25%CO2 use two volts less than shown.
*DC-Electrode positive **Arc voltage is measured at wire feeder.
