Working Environment
1) Welding should be carried out in dry environment with its humidity of 90% or less.
2) The temperature of the working environment should be between -10°C to 40°C.
3) Avoid welding in the open air unless sheltered from sunlight and rain. Keep it dry anytime and do not place
it on wet ground or in puddles.
4) Avoid welding in dusty area or environment with corrosive chemical gas.
5) Gas shielded arc welding should be operated in environment without strong airflow.
Safety Tips
Over-current/over-voltage/over-heating protection circuit is installed in this machine. If the input voltage or the
output current is too high or machine inside temperature over heating inside, the machine will stop automati-
cally. However, excessive use (e.g. too high voltage) of machine may also damage machine, so please note:
1)
Ventilation
High current passes when welding is carried out, thus natural ventilation can not satisfy the machine’s
cooling requirement. Maintain good ventilation through the louvers of the machine. The minimum distance
between the machine and any other objects in or near the working area should be 30cm. Good ventilation
is of critical importance for the normal performance and lifespan of the machine.
2) Welding operation is forbidden while the machine is overload.
Remember to observe the max load current at any moment (refer to the corresponding duty cycle). Make
sure that the welding current should not exceed the max load current. Overload could obviously shorten
the machine’s lifespan, or even damage the machine.
3)
Over-voltage
is
forbidden.
Regarding the power supply voltage range of the machine, please refer to “Main Parameters” table. This
machine 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 would possibly damage the
components of the machine.
4) A sudden halt may occur while the machine is of overload status. Under this circumstance, it is unneces-
sary to restart the machine. Remain the built-in fan working to lower the temperature inside the machine.
