SAFETY
CAUTION
1.Working Environment.
1.1 The environment in which this welding equipment is installed must be free of
grinding dust, corrosive chemicals, ammable gas or materials etc, and at no
more than maximum of 80% humidity.
1.2 When using the machine outdoors protect the machine from direct sun light,
rain water and snow etc;the temperature of working environment should be
maintained within -14°F to +104°F.
1.3 Keep this equipment distant from the wall.
1.4 Ensure the working environment is well ventilated.
2.Safety Tips.
2.1 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 operation. Important: Maintain good
ventilation of the louvers of this equipment. The minimum distance betweenthis
equipment and any other objects in or near the working area should be 1ft.
Good ventilation is of critical importance for the normal performance and
service life of this equipment.
2.2 Thermal Overload protection.
Should the machine be used to an excessive level, or in 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 safe level.
2.3 Over-Voltage Supply
Regarding the power supply voltage range of the machine, please refer to“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.
2.4 Do not come into contact with the output terminals while the machine is in
operation. An electric shock may possibly occur.
