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.

J. Cutting Technique
Hold the torch with one or two hands, with the torch tip close to the workpiece. Do not cut or handle the work-
piece without welding gloves and protective clothing. Always wear protective eye shielding when cutting or
gouging. Move the torch along the cut line so the arc penetrates the workpiece and sparks emerge from the
bottom of the cut. Good cutting speeds create a slight trailing arc.
K. Postflow
Release the trigger to stop the cutting arc. Gas continues to flow for approximately 10 seconds. During post
- flow, if the user moves the trigger release to the rear and presses the trigger, the pilot arc starts. The main arc
transfers to the workpiece if the torch tip is within transfer distance to the workpiece.
l. Shutdown
Turn the ON / OFF switch to OFF (down). All Power Supply indicators shut off. Unplug the input power cord
or disconnect input power. Power is removed from the system.
