environment should be maintained within -10°C to +40°C.
1.3 Keep this welding & cutting equipment 30cm distant from the wall.
1.4 Keep the working environment in good ventilation.
2. Safety tips
2.1 Ventilation
This welding & cutting equipment is small-sized, compact in structure and of
excellent performance in current output. Fans are required to abstract heat
generated by this cutting equipment while the operation of welding is
carried out.
Cautions:
Maintain good ventilation of the louvers of this welding &
cutting equipment. The minimum distance between this welding & cutting
equipment and any other objects in or near the working area should be 30
cm. Good ventilation is of critical importance for the normal performance
and service life of this welding & cutting equipment.
2.2 Welding operation is forbid while this welding & cutting equipment is of
over-load.
A sudden halt may occur while the cutting operation is carried out while this
welding & cutting machine is of over-load status. Under this circumstance, it
is unnecessary to restart this welding & cutting equipment. Keeps the
built-in fan working to bring down the temperature inside this welding &
cutting equipment.
2.3 Over-voltage is forbid.
Regarding the power supply voltage range of the welding & cutting machine,
please refer to "Main parameter" table. This welding & cutting equipment is
of automatic voltage compensation, which enables the maintaining of the
voltage range within the given range. In case that the voltage of input
power supply current exceeds the stipulated value, it is possibly damaging
to the components of this welding & culling equipment.
2.4 An earth terminal available for this welding & cutting equipment. Connect
with the earth cable to avoid the static and electric shock.
It is strongly forbid to contact the output terminal when the welding &
cutting operation is performed. An electric shock possibly occurs.
Exposure to extremely dusty, damp, or corrosive air is damaging to this welding
& cutting machine. In order to prevent any possible failure or fault of this
welding & cutting equipment, clean the dust at regular intervals with clean and
dry compressed air of required pressure.
Please note that: lack of maintenance can spell to the unavailability and
cancellation of the guarantee; the guarantee of this welding & cutting equipment
will be no longer available in case that it has been attempted to take the
machine apart or the open the factory-made sealing of the machine.
CAUTIONS Only the qualified technicians are authorized to undertake the repair
task of this welding & cutting equipment in case of machine fault.
Fault Symptoms
1. While this welding &
cutting equipment is
off, the built-in fan is
not functioning, and
there is no output.
MAINTENANCE
TROUBLESHOOTING
1. Possible damage of power supply switch,
compensate the damage if necessary.
2. Possible unavailability of power supply. Check and
compensate the failure if necessary
3. Possible short-circuit of the input cable. Check it
