I. Cutting Operation
Refer to Section 1, Important Safety Precautions. Wear heavy welding gloves and protective clothing. Protect
eyes with appropriate shielding. Aim the torch head away from yourself. Slide the trigger release to the rear.
Squeeze and hold the trigger. Gas flows for approximately 1 second, then shuts off briefly. The pilot arc then
starts. DC indicator
turns on. Bring the torch within transfer distance to the workpiece. The pilot arc stops
and the main arc transfers to the workpiece.
NOTE
When operating the torch in a normal condition, a small amount of gas vents through the gap between the shield
cup and torch handle. Do not attempt to over tighten the shield cup as irreparable damage to internal components
may result.
