Torch trigger/Gas test switch - (4)
Operating modes:
Normal trigger (CENTER position) - Setting will be used for most cutting and gouging
operations. The torch switch must be held in by the operator during the entire cutting
operation and then released at the end of cut. Recommended for normal cutting,
expanded metal/grate cutting and gouging.
Trigger lock (DOWN position) - allows the torch switch to be released after triggering
and the cutting arc has been initiated. To extinguish the arc at the end of the cut,
press and release the torch switch again or pull the torch away from the work piece.
Not recommended for expanded metal/grate cutting.
Test mode:
Gas test switch (UP position) - The display will indicate flowing air pressure. The air
regulator should be adjusted to recommended pressure before cutting operations.
Allow air to flow for a few minutes. This should remove any condensation that may
have accumulated during a shutdown period. Be sure to place the switch in normal
trigger or trigger lock position before starting any cutting operations.
Pressure regulator - (5)
Regulates torch air pressure. Rotate clockwise to increase and counterclockwise to
decrease.

5.3 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 mains voltage switch to I (On).
4. Flip the toggle switch upwards to gas test mode (GAS TEST). Set the pressure
regulator to 5.5 bar (80 psi).
5. Set the toggle switch to normal mode (CENTER) or trigger lock mode (DOWN).
6. 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. When not using
the stand-off guide, the nozzle should be held approximately 3.2 mm - 6.4 mm
from the work.
7. Depress the torch switch. Air should flow from the torch nozzle.
8. Two seconds after depressing the torch switch, the pilot arc should start. The
main arc should immediately follow, allowing the cut to begin. (If using the
TRIGGER LOCK feature, the torch switch may be released after establishing the
cutting arc.)
9. To start a cut, tilt the torch to prevent molten material from coming back against
and damaging the torch. When the arc breaks through the workpiece, bring the
torch to an upright position and proceed to cut.
10. When ending a cut, the torch switch should be released (press and release if
using TRIGGER LOCK feature) and the torch lifted off the workpiece
immediately upon completion of the cut. This is to prevent the pilot arc from
re-igniting after cutting arc extinguishes and causing damange to the nozzle
(double arcing).
11. For rapid re-starts, such as grate or heavy mesh cutting, do not release the torch
switch. In the postflow mode, the arc can be re-started immediately by
depressing the torch switch. This avoids the 2-second preflow portion of the
cutting cycle.
