45 Service Manual
Start a cut from the edge of the workpiece
• If you fire the torch unnecessarily, you shorten the
life of the nozzle and electrode.
• Pulling, or dragging, the torch along the cut is easier
than pushing it.
• For straight-line cuts, use a straight edge as a
guide. To cut circles, use a template or a radius
cutter attachment (a circle cutting guide). See the
Parts section for part numbers for the Hypertherm
plasma cutting guides for cutting circles and making
bevel cuts.
• Hold the torch nozzle perpendicular to the
workpiece so that the nozzle is at a 90° angle to the
cutting surface, and watch the arc as it cuts along
the line.
1. With the work clamp attached to the workpiece,
hold the torch nozzle perpendicular (90°) to
the edge of the workpiece. If you are using the
shielded consumables, no standoff is needed. With
unshielded consumables, maintain an approximate
2 mm (0.08-inch) standoff.
