5.4 Cutting
1. Set the switch (wall socket or similar) to on.
2. Check that the compressor is connected to the power source.
3. Set the power switch to I (On).
4. After starting the cut, the torch should be maintained at a 5 - 15° forward angle.
This angle is especially useful in helping to create a “ drop ” cut. The torch can be
operated with the nozzle dragging on the plate or with up to 6.35 mm standoff.
The ideal standoff is 3.2 mm. Standoff guides are available to simplify
maintaining the gap, see wear parts on page
27 .
5. Depress the torch switch. Air should flow from the torch nozzle.
6. Two seconds after depressing the torch switch, the pilot arc should start. The
main arc should immediately follow, allowing the cut to begin.
7. To start a cut, tilt the torch to prevent molten material from splashing back and
damaging the torch. When the arc breaks through the workpiece, bring the torch
to an upright position and proceed to cut.
8. When ending a cut, the torch switch should be released and the torch lifted off
the workpiece immediately upon completion of the cut. This is to prevent the pilot
arc from re-igniting after the cutting arc has extinguished and causing damage to
the nozzle (double arcing).
9. For rapid re-starts on machines that support grate cutting mode, do not release
the torch switch. The torch will automatically return to pilot arc mode after each
cut and transfer back to main arc, when the torch is positioned over the next
working surface. When working without grate cutting mode, simply release and
re-press the trigger during the postflow to restart the arc without a delay for
preflow.
