MIG -160/200
6.4.2 Operation method
1) After being installed according to the above method, and with the power switch on, the machine starts with
the power LED on and the fan working. Open the cylinder valve and adjust the flow regulator to get the
proper gas flow.
2) Switch the MMA/MIG shift switch to MIG mode, and select proper welding voltage and welding current by
adjusting the voltage control knob in MIG and wire feed speed control knob in MIG on the front panel of the
machine.
3) Welding can be carried out by pushing the torch trigger on the welding torch.
4) 1 second after the arc stops, the gas supply will be cut off.
7.1 Working environment
1) The product shall be operated under dry environment with normal humidity under 90%.
2) The temperature of working environment should be between -10 and 40 .
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) Avoid working in the environment where the air circulation is too strong
6) Gas shielded arc welding should be operated in environment without strong airflow.
7.2 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 cannot 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.
