INITIATING OPERATION
A. Unpacking
Unpack all the items out of the box and make sure that you have received all items listed on the
packing list.
B. Work environment
Make sure that the work area is well ventilated. The unit is cooled by an axial fan that provides
an air flow for the electronics through the rear panel. (Note! The housing must be installed in a
way that ensures that the vent holes are closer to the front of the machine). At least 15 cm at the
front and 15 cm on each side should be left to enable cleaning. If the machine is operated without
adequate cooling, the length of the duty cycle will be reduced greatly.
C. Cable connections
Each unit is equipped with a main power cable, which is responsible for providing current and
voltage to the device. If the device is connected to power which exceeds the required voltage,
or if the wrong phase is set, it may lead to severe damage to the unit. This is not covered by the
warranty for the equipment and the user will be responsible for such situations.
D. Torch connection
Connect the torch to the inverter by connecting the air tube that is attached at the end of the
torch to the torch connector on the front part of the machine. Ensure that the connection is
secure by tightening it slightly with a spanner. However you should not make it too tight.
A. Assembling the pistol
Put the pistol the protective cap facing up and turn the cap away from the gun. (The protective
cap holds the tip, the ceramic swirl ring and the electrode together). Remove the cap, the ceramic
swirl ring and the electrode. Assemble the electrode, the ceramic swirl ring and the tip back
together. Replace worn parts if necessary. Put the protective cap on the head of the pistol and
screw it on with your hand until it is snug. If any resistance is present during this process, check
the thread and the arrangement of the items before resuming work.
NOTE
In case of some pistols with no reversible electrodes it is necessary to tighten the electrode
further by using a pair of pliers in order to ensure a reliable electrical connection.

INSTRUCTIONS FOR USE
A. The beginning
Turn the power switch to „ON". Take up a position at the unit in which you can easily read the
air pressure from the device. Press the pistol switch (air will flow out from the pistol), adjust
the air valve to approximately 4-5 (bar) and press the pistol switch again.
NOTE
The generally accepted value range of air pressure is 4-5 bar. You can now perform tests as
needed, but you should remember not to reduce the air pressure too much because it may
damage the consumables. Secure the grounding clamp on the workpiece. Connect the clamp to
the main part of the workpiece and not to part which is to be removed.
B. CUTTING
1. Drag-cutting
Hold the tip of the pistol above the workpiece, press the pistol switch and move the pistol
tip until it comes into contact with the workpiece and the cutting arc is established. Once the
cutting arc is generated you may move the pistol in the desired direction with the tip of the
pistol always at a slight angle and maintaining contact with the workpiece. This working method
is called drag cutting. Excessively rapid movements should be avoided. A sign of this are sparks,
which can spray from the top of the workpiece. Move the pistol with a speed that ensures gat-
hering of the sparks under the workpiece and before proceeding make sure that the material is
cut through completely. Set the drag speed as required.
2. Weekly activities
Verify the proper operation of the air flow. Blow off or suck in dust or dirt from the entire
machine, including the air filter.
3. Distance cutting
In some cases it may be advantageous to perform cutting with the tip of the pistol at a height
of approximately 1/16" to 1/8" above the workpiece in order to reduce the amount of material
which is once again blown back into the tip and to maximize the penetration of thick cuts
through the material. Distance cutting should be used when penetration cutting or or grooving
is executed. The distance technique may also be used when cutting sheet metal in order to
minimize the risk of material back splashing, which could damage the tip.
4. Drilling through
In order to drill through the tip of the pistol should be placed at approximately 3,2 mm above
the workpiece. Hold the pistol at a slight angle to deflect the sparks away from yourself and
the tip of the pistol. Activate the main arc and lower the tip of the pistol until the main cutting
arc is initiated and sparking begins. Initiate drilling on a test item which is no longer in use and
continue with the drilling on the previously defined cut line once the test hole is completed
without problems.
MAINTENANCE
Check the pistol for wear damage, cracks or exposed wire sections. Replace or repair any such
defects before using the device. A heavily worn pistol tip/nozzle contributes to the reduction of
speed, voltage drops and crooked cuts. An indication of a worn pistol tip/nozzle is an elongated
or oversized nozzle opening. The external part of the electrode may be recessed no more than
3.2 mm. Replace the electrode if it is worn, as indicated by the above measurement. If the cap
cannot be re-attached easily, check the thread.
