Recommended Settings

Recommended shielding gas can be 100% CO2 however use of 75% Argon – 25% CO2 will improve usability especially for out of position applications. Increasing the percentage of Argon in the Argon – CO2 mixture will increase the yield and tensile strengths.

Use Reverse Polarity (DCEP)

Recommended Settings:
.035 Diameter – 22-28 volts, 125-225 amps, 1/2″ – 3/4″ stick out
.045 Diameter – 22-30 volts, 160-300 amps, 1/2″ – 3/4″ stick out
1/16 Diameter – 23-29 volts, 225-400 amps, 1/2″ – 3/4″ stick out

Best Practices

Applications include structural fabrication, construction equipment, pipe weldments, storage tanks, pressure vessels, truck frames and all crack sensitive steels.
We recommend Gemini Anti-Spatter spray for lasting protection of your contact tip and MIG nozzle (see chemical aids in Abrasives & Metal Working products section).
