2 INSTALLATION
After connecting electric power and compressed air, the machine is ready for use.
If installing machine on 110V supply the required fuse size is 32A.
NOTE: at least 7.5 kVA should be available from the generators exclusively for the plasma cutting system. If
available power is lower it may result in major damage to the power source.
Air supply
Connect dry, clean and oil free compressed air with minimum pressure 4 bar, maximum pressure 9 bar to
the filter regulator on the rear of the machine.

3 OPERATING INSTRUCTIONS
Check that the machine has been properly connected to power supply and compressed air according
to chapter 2, INSTALLATION.
Check that the torch is fitted with appropriate consumables for the job at hand.
Connect the return clamp directly onto the work piece, ensuring that a good contact is obtained.
If necessary, clean the surface from paint, rust, dirt, etc.
Switch the machine’s power switch on. The green power led will light and the fan will start working.
Choose process power, 5-30 Ampere.
Press trigger shortly to start the pilot arc, release the trigger and adjust during post flow: 3.5 bar.
Cutting
Place the torch in position for cutting with the nozzle in direct contact
with the material to be cut.
Lift the trigger protection and press the trigger-switch on the torch
handle.
The pilot arc strikes immediately.
The pilot arc will burn for about 5 seconds.
If contact with the work piece is not obtained within this time, the pilot
arc goes out.
Reposition the torch to ensure that the pilot arc will reach the workpiece and make a new try.
When the cutting arc is established, pull the torch slowly across the
surface that is to be cut. At correct speed the sparks goes straight
through the metal with only a slight bending towards the beginning of
the cut
Pause briefly at the end of cut before releasing the trigger.
The plasma arc goes out immediately. Air will continue to flow for
about 15 seconds. When removing the finger from the trigger the
trigger protection will close over the butt on.

Piercing
Rest the nozzle on the
work piece at 45° angle
Press the trigger-switch on the torch handle.
Pilot arc strikes.
After cutting arc starts, slowly and in one smooth movement,
straighten torch back up until 90° angle to plate.
Start moving torch across plate when observing that the arc
penetrates.
Circle cutting guide (optional accessory)
The wheeled wagon in the circle cutting set shou ld be used when
cutting on uneven surfaces where it is difficult to use the drag
shield.
1. Pull off the distance cutting guide (if mounted)
2. Insert the torch into the cutting wagon.
3. Tighten the allen screw on the inner ring.
4. Tighten the allen screw on the outer ring with the wheels
axis at 90° to the torch handle
For cutting circles the allen screw in point 4 must be loosened to
allow the torch to rotate in the wagon.
The circle cutting bar is screwed into the wheel centre, and the
centre tap is fastened at the correct radius.
NOTE!
When the machine is not in use or is only working at long intervals, switch off the machine. It contains
mechanical components that should not be exposed to unnecessary wear. It also protects against
accidental firing the pilot arc.

5. MAINTENANCE
DAILY
Inspect and, if necessary, change the torch consumable parts.
Note:
Electrode and nozzle must be changed at regular intervals, as a general guideline after 2 hours
continuous use, or after 200 starts.
Always replace the electrode if the centre has a pit more than 2 mm (1/16” deep). Replace the nozzle if
the opening is deformed or clearly oversized.
Failure to replace worn nozzle or electrode in time will dramatically reduce the cutting capacity and
eventually ruin the torch.
The moisture trap on the backside of the machine is self relieving by pressure drop, this means that
every time you start and stop a cutting cycle it will drain the moisture in the trap. If cleaning or manual
emptying of the trap is necessary, completely unscrew the glass cup after disconnecting compressed
air.
Carefully inspect the hose assembly and torch body with regard to any leak or damage.
Never use a damaged torch.
EVERY THREE TO SIX MONTHS
Disconnect the machine from compressed air and electricity.
Remove the cover.
Clean the machine with dry, clean and oil free compressed air. Inspect cable connections and gas
system.
In especially dirty environments this procedure should be carried out more often.
