Hand torch cutting guidelines
 Drag the torch tip lightly on the workpiece to maintain a steady cut speed.

With drag-cutting, it is normal to experience the torch sticking slightly to the workpiece.
 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 212 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
 Do not operate the system on a 15 A circuit.
 Do not use an extension cord.
 Make sure nothing else is drawing power from the circuit.
 Turn down the current adjustment knob to avoid tripping the breaker.
