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 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 Section 6, Parts, for part numbers for the Hypertherm plasma cutting
guides for cutting circles and making bevel cuts.
• With either the 75-degree or 15-degree hand torch, 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.
