Hand torch cutting hints
• With shielded consumables, drag the nozzle lightly along the workpiece to maintain a steady
cut. With unshielded consumables, maintain an approximate .08-inch (2 mm) distance
between the tip of the torch and the workpiece. (This is between a 1/16th and 1/8th of an
inch).
• 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.
• 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.
