Hand torch cutting hints
• Drag the torch tip lightly along the workpiece to maintain a steady cut.
• While cutting, make sure that sparks exit from the bottom of the workpiece. The sparks
should lag slightly behind the torch as you cut (15° — 30° angle from vertical).
• If sparks spray up from the workpiece, move the torch more slowly, or set the output
current higher.
• If you fire the torch unnecessarily, you will
shorten the life of the nozzle and electrode.
• Pulling, or dragging, the torch along the cut is easier than pushing the torch.
• 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 Section 4, Maintenance and Parts,
for part numbers for the Hypertherm plasma cutting guides for cutting circles and making
bevel cuts.
• With hand torches, hold the torch nozzle
perpendicular to the workpiece so that the
nozzle is at a 90° angle to the cutting surface.
Observe the cutting arc as the torch cuts.
