E. 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). Re-
move 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 elec-
trode further by using a pair of pliers in order to ensure a reliable electrical connection.
INSTRUCTION
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 6-7 (bar) and press the pistol switch again.
Note
The generally accepted value range of air pressure is 5-8 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 ground terminal 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 pi-
stol 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 gathering 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.
F. TIG cutting torch
Take the pistol in your hand and first turn the small black cap (back cup). Now turn
to the long black cap. Put the the tungsten electrode into the clamping sleeve (Collet).
Then insert the collet body and screw the ceramic head (nozzle) to the front part of
the pistol.
