Hand Torch Cutting Hints - Hypertherm powermax 65 Operator's Manual

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.
• 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.
• 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.
