Procedure when using an external compressor
PLEASE NOTE:
For plasma cutting, a pressure of 4–4.5 bar is recommended. Adjust this accord-
ingly on your compressor. Please bear in mind that the pressure can lower while setting the air pressure.
Thus, in a hose length measuring 10 m and an internal diameter of 9 mm it drops by approx. 0.6 bar.
The compressed air source must have a filter and regulator.
Connect the compressed air hose
20
on the back of the plasma cutter
1
to the compressed air
connection
17
. To do so, insert the side of the compressed air hose into the compressed air
connection
17
of the plasma cutter
1
without a quick connector (see Fig. I).
The pressure can be adjusted using the pressure regulator on your compressor. Select a pressure of
4–4.5 bar.
In order to release the compressed air hose
20
again, you must press the locking mechanism of the
compressed air connection
17
and pull out the compressed air hose
20
at the same time (see Fig. I).
Switch the toggle switch for external compressed air
18
to the “open” position (Figure M).

Connecting the cutting burner
Remove the cover
21
of the connection socket
13
.
Insert the plasma burner plug
7
into the plasma burner connection socket
13
and tighten the plasma
burner plug hand-tight
7
(see Fig. A+B).
Plug the plasma burner control plug
6
into the plasma burner control socket
11
and tighten the union
nut hand-tight (see Fig. A+B).
z
Connecting the earthing cable
Connect the earthing terminal plug
5
with the earthing terminal connection socket
12
.
Make sure that the connecting shaft is first connected and then turned. The connecting shaft must face
upwards when plugging in the earthing cable plug
5
. After plugging in, the connecting shaft must be
rotated in a clockwise direction until it reaches the stop, in order to lock it in place (see Fig. A+B).
This does not require force!

Fitting the removable roller guide (optional)
Push the removable roller guide
19
over the nozzle clamping sleeve
8b
, until the locking screws
19a
are
completely above the black area of the plasma burner
8
(behind the gap at the back of the nozzle
clamping sleeve
8b
) (see Fig. N). Now fix the locking screws
19a
. The guide rollers
19c
are now
positioned such that the required distance between the workpiece and burner sleeve
8c
is set. The roller
guide is then fixed in place
19
by tightening the fixing screws
19b
(see Fig. N). Make sure that both
guide rollers
19c
are always set to the same height, in order to enable straight cutting. You can see a
correctly fitted roller guide in Fig. N.

Operation
1. Set the plasma cutter
1
up in a dry and well ventilated area.
2. Position the machine in the vicinity of the workpiece.
3. Clamp the earthing terminal
4
onto the workpiece to be cut and make sure that there is a good
electrical contact.
4. Press the on/off switch
16
.
5. Set the cutting current on the current controller
14
. If the arc beam is interrupted the cutting current
