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.
