Hand torch cutting guidelines
With either set of consumables, drag the torch tip lightly on the workpiece to maintain a steady cut speed.
Sometimes the torch sticks slightly to the workpiece when you cut with the FineCut
consumables.
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, you are not cutting all the way through the workpiece. Move the torch more slowly, or, if possible,
increase the output current.
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.
Pulling the torch toward you along the cut is easier than pushing it or moving from side-to-side.
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 Accessory parts on page 195 for the Hypertherm plasma cutting guide part numbers for
cutting circles and making bevel cuts.
If you fire the torch unnecessarily, you shorten the life of the nozzle and electrode.
Recommendations for cutting at 120 V
Use only the FineCut consumables.
Do not use an extension cord.
Verify nothing else is drawing power from the circuit.
Turn down the current adjustment knob to avoid tripping the breaker.
