CAUTIONS
1. Working Environment
1.1The location in which this welding equipment is installed should be of little
dust, corrosive chemical gas, flammable gas or materials etc, and of
maximum 80% humidity;
1.2Avoid the operation of welding in the open air unless the working area
sheltered from the sun shining, rain water and snow etc; the temperature of
working environment should be maintained within -10°C to +40°C;
1.3 The minimum distance of this welding equipment and wall should be 30cm.
1.4 Keep the working environment in good ventilation.
2. Safety Tips
2.1 Ventilation
This welding equipment is small-sized, compact in structure and of excellent
performance in current output. Fans are to abstract heat generated by this
welding equipment while the operation of welding is carried out.
Cautions: Maintain good ventilation of the louvers of this welding equipment.
The minimum distance between this welding 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
equipment.
2.2 Welding operation is forbid while this welding equipment is of over-load.
A sudden halt may occur while the welding operation is carried out while this
welding machine is of over-load status. Under this circumstance, it is
unnecessary to restart this welding equipment. Keeps the built-in fan working
to bring down the temperature inside this welding equipment.
2.3 Over-voltage is forbid.
Regarding the power supply voltage range of the welding machine, please
refer to “Main parameter” table. This welding equipment is of automatic
voltage compensation, which enables the maintaining of the voltage range
within the given range. In case that the input voltage exceeds the stipulated
value, it is possibly damaging to the components of this welding equipment.
2.4 An earth terminal available for this welding equipment. Connect with the
earth cable to avoid the static and electric shock.
2.5 It is strongly forbid to contact the output terminal when the welding
operation is performed. An electric shock possibly occurs.
MAINTENANCE
Exposure to extremely dusty, damp, or corrosive air is damaging to the welding
machine. In order to prevent any possible failure or fault of this welding 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 equipment will be no
longer available in case that it has been attempted to take the machine apart or
open the factory-made sealing of the machine.
