Before use / Using the device
distance between the workpiece and burner
sleeve 8c is set. The roller guide is then fi xed
in place 19 by tightening the fi xing screws
(see Fig. N). Make sure that both guide
19b
rollers are always set to the same height,
19c
in order to enable straight cutting. You can
see a correctly fi tted roller guide in Fig. N.

• Using the device

• Operation

1. Set the plasma cutter
well ventilated area.
2. Position the machine in the vicinity of the
workpiece.
3. Press the on/off switch
4. Clamp the ground terminal
workpiece to be cut and make sure that
there is a good electrical contact.
5. Set the cutting current on the current
controller 14 . If the arc beam is inter-
rupted the cutting current must be set
higher if necessary. If the electrode burns
through frequently, then the cutting
current must be set lower.
6. Position the plasma cutter
workpiece so that the burner sleeve
free and that a blowback of the molten
metal is not possible. Press the plasma
burner button 8a . The transmitted cutting
arch is ignited on the edge of the sheet
in this manner.
7. Start cutting slowly and then increase the
speed in order to achieve the desired
cutting quality.
8. The speed must be regulated so that a
good cutting capacity can be achieved.
The plasma beam creates a straight arch
(stainless steel, aluminium) or a 5° arch
of approach (soft steel).

To cut in the manual cutting mode,
pull the overlying burner across the
workpiece while maintaining a
constant speed. To achieve the perfect cut,
it is important for the material thickness to
comply with the correct cutting speed. If the
cutting speed is too low, the cutting edge will
be blunt due to the severe heat input. The
optimal cutting speed is achieved once the
cutting jet is slightly inclined towards the rear
while cutting. If the plasma burner button
is released, the plasma jet goes out and the
power source switches off. The gas continues
to fl ow for approx. 5 seconds in order to
cool the burner. The same process is
followed when the workpiece is pulled out
with a pressed plasma burner button
During the gas post-fl ow time, the plasma
cutter must not be switched off to avoid
1
damaging the plasma burner
of overheating.
ATTENTION!
The device must be left on for approx.
2–3 minutes once the cutting work has
been completed. The cooler cools the
electronics.

• Types of plasma cutting

Drag cutting
Hold the tip of the burner sleeve
the workpiece and press the plasma burner
button 8a . Now move the burner sleeve until
8c there is contact with the workpiece and
the cutting arch is fi xed. Once the cutting
arch has been generated, move the plasma
burner 8 in the desired direction. Makes
sure that burner sleeve is slightly
and that contact with the workpiece is
maintained. This working method is called
drag cutting. Avoid quick movements. A sign
