I. Cutting Operation
Refer to Section 1, Important Safety Precautions. Wear heavy welding gloves and protective clothing. Protect
eyes with appropriate shielding. Refer to the torch manual for torch operation details.
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
workpiece 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.
