OPERATING MANUAL
Caution
Working environment
• The environment in which this welding/cutting equipment is installed must be free of grinding dust, corrosive chemicals,
flammable gas or materials etc., and at no more than a maximum of 80% humidity.
• When using the machine outdoors, protect the machine from direct sunlight, rainwater and snow, etc.; the temperature
of the working environment should be maintained within -10°C to +40°C.
• Keep this equipment 30cm distant from the wall.
• Ensure the working environment is well ventilated.
Safety tips
•
Ventilation:
This equipment is small-sized, compact in structure, and of excellent performance in amperage output.
The fan is used to dissipate heat generated by this equipment during the welding/cutting operation. Important: Maintain
good ventilation of the louvres of this equipment. The minimum distance between this 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 equipment.
•
Thermal Overload Protection:
Should the machine be used to an excessive level, or in a high-temperature
environment, poorly ventilated area or if the fan malfunctions the Thermal Overload Switch will be activated, and the
machine will cease to operate. Under this circumstance, leave the machine switched on to keep the built-in fan working
to bring down the temperature inside the equipment. The machine will be ready for use again when the internal
temperature reaches a safe level.
•
Over-Voltage Supply:
Regarding the power supply voltage range of the machine, please refer to the “Main parameter”
table. This 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 amperage exceeds the stipulated value, it is possible to
cause damage to the components of this equipment. Please ensure your primary power supply is correct.
• Do not come into contact with the output terminals while the machine is in operation. An electric shock may occur.
Maintenance
Exposure to extremely dusty, damp, or corrosive air is damaging to the welding/cutting machine. 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 result in the cancellation of the guarantee; the guarantee of this welding/
cutting equipment will be void if the machine has been modified, attempt to take apart the machine or open the factory-
made sealing of the machine without the consent of an authorized representative of the manufacturer.
Troubleshooting
Caution:
Only qualified technicians are authorized to undertake the repair of this welding/cutting equipment. For your
safety and to avoid Electrical Shock, please observe all safety notes and precautions detailed in this manual.
