Instruction Notes
Working Environment
1. The location in which this welding & cutting equipment is installed should be free of dust, corrosive
chemical gases, flammable gases or materials, and be at no more than 80% humidity.
2. Avoid welding & cutting in the open air unless sheltered from the sun, rain, and snow.
The temperature of the working environment should be maintained within -10°C to +40°C.
3. Keep this welding & cutting equipment 30cm away from the wall.
4. Ensure the working environment has good ventilation.
Safety
a) Ventilation
This welding & cutting equipment is small, compact in structure, and has excellent current output
performance. Fans are required to remove heat generated by this cutting equipment while the machine
is being operated.
Cautions: Maintain good ventilation of the louvers of this welding & cutting equipment. The minimum
distance between this welding & cutting equipment and any other object 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.
b) Welding cannot be performed if equipment is overloaded.
A sudden halt may occur while the cutting operation is carried out if the machine is in over-load status.
Under this circumstance, it is unnecessary to restart the equipment. Keep the built-in fan running to
bring down the temperature inside the equipment.
c) Beware of over-voltage.
Regarding the power supply voltage range of the welding & cutting machine, please refer to the
“Specifications” table. This equipment has automatic voltage compensation, which enables it to maintain
the voltage within the given range. If the power supply input voltage current exceeds the stipulated
value, it is possible to damage the components of this equipment.
d) An earth terminal is available for this welding & cutting equipment.
Connect the earth cable to avoid static and electric shock. It is not recommended to touch the output
terminal while welding and cutting. An electric shock may occur.
