part of yourself or anyone else. Do not overuse or
overheat your device.Do not point cutting torch
at any body part of yourself or anyone else.
NOTE
This is a sensitive electronic device, do not abrupt-
ly change or adjust the cutting current, otherwise
the device will be damaged.
On the machine you will find the data table with
the below information:
X = Duty cycle
I1 = Rated input current
I2 = Rated cutting current
U0 = No load rated voltage
U1 = Rated input voltage
U2 = Rated load voltage
SETTING UP THE UNIT
Make sure there is at least 50cm free space around
the machine in order to have good ventilation.
Connect the power supply cable (Fig. 1.2) to the power
f
supply.
Connect the gas supply hose to the gas supply connec-
f
tor (Fig. 1.4) on the back of the machine.
Connect the ground clamp to the ground clamp con-
f
nector (Fig. 1.12) on the front of the machine.
Connect the cutting torch to the cutting torch connec-
f
tor (Fig. 1.13) on the front of the machine.
When the supply power is on, the input power
supply voltage is shown on digital display. Turn
the ON/OFF switch (Fig. 1.1) to ON position and
observe if the operation state is normal and that
the cooling fan (Fig. 1.3) starts up as supposed.
The power supply indicator (Fig. 1.16) should lit. If
there is no gas or the gas pressure is not enough,
the gas pressure indicator will lit. Adjust the gas
supply valve till the pressure is up to the cutting
operation requirement and no less than 0.33MPa.
Adjust the air flow and observe if the air flow is
smooth.
NOTE
2T function (Fig. 1.9) means that the trigger of the
cutting torch is required to be engaged constantly
while cutting. 4T function (Fig. 1.10) means that
the trigger of the cutting torch is engaged once
to ignite the arc, and it will stay ignited until you
engage the trigger again to turn it off. You can
change between these modes by pressing the
trigger mode selector (Fig. 1.11).
MANUAL CONTACT CUTTING
Place the cutting torch's nozzle at the start of the
work piece, slightly touching (Fig. 3.1). Engage the
torch trigger to ignite the plasma. After the work
piece is cut thoroughly, move the cutting torch
along the cutting direction (Fig. 3.2) uniformly.
If the movement of the torch on the work piece
is too quick, the work piece will not be cut very
thoroughly, If the movement of the torch on the
work piece is too slow, the cut quality would be af-
fected. Turn off the cutting torch after cutting to
extinguish the plasma and then withdraw it from
the workpiece.
MANUAL NON CONTACT CUTTING
Adjust the space between the work piece (Fig.
4.2) and the nozzle (Fig. 4.1) between 2mm and
4mm. Engage the torch trigger to ignite the plas-
ma. After the work piece is cut thoroughly, move
the cutting torch along the cutting direction uni-
formly. If the movement of the torch on the work
piece is too quick, the work piece will not be cut
very thoroughly, If the movement of the torch on
the work piece is too slow, the cut quality would
be affected. Turn off the cutting torch after cut-
ting to extinguish the plasma and then withdraw
it from the workpiece.
TROUBLESHOOTING
Refer to the respective table at the end of the
manual. Regarding any failures not described in
that table cause identification and correction op-
erations must be carried out by your dealer or an
authorized service centre.
MAINTENANCE AND CLEANING
WARNING
For your own safety, turn the switch off and re-
move plug from power source outlet before any
operation of maintenance on the machine. Keep
your appliance clean. In order to avoid over heat-
ing, regularly check the air openings for any dust
sticking on. After a longer period of use, it is rec-
ommended to have the machine checked by an au-
thorized dealer service. Connections and repairs
of electrical equipment may only be carried out by
an electrician.
POWER CORD
To avoid shock or fire hazard, if the power cord is
worm or cut, or damaged in any way, have it re-
placed immediately. Electrical connection cables
often suffer insulation damage. Possible causes
are:
Punch points when connection cables are run through
f
window or door gaps.
Kinks resulting from incorrect attachment or laying of
f
the cable.
Cuts resulting from running over the cable.
f
Insulation damage resulting from forcefully pulling
f
out of the wall socket.
Cracks through aging of insulation.
f
Such defective electrical connection cables must
not be used as the insulation damage makes them
extremely hazardous.
CLEANING
Use a small soft brush to clean the outside of the
unit. Do not use strong detergents. Household
cleaners that contain aromatic oils such as pine
and lemon and solvents such as kerosene can
damage plastic housing or handle. Wipe off any
moisture with a soft cloth. Remove dust, dirt and
machining residues with an appropriate vacuum
cleaner if necessary.
