SMART MIG 350 MPV1
6. CAUTION.
6.1. Working Environment
1) Welding should be carried out in dry environment with humidity of 90% or less.
2) The temperature of the working environment should be between -10℃ and 40℃.
3) Avoid welding in the open air unless sheltered from sunlight and rain. Keep welder dry
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.
6.2. Safety Tips
Over heating protection circuit is installed in this machine. When machine's inner temperature exceeds the setting
standard, it will stop working automatically. However, excessive operation will lead to welder damage. Therefore,
please note:
1) Ventilation
There will be large current during operation and will require strict cooling devices instead of natural
ventilation. Therefore the built-in two fans are very important to ensure effective cooling and stable working
performance. The operator should make sure that the louvers be uncovered and unblocked. The minimum
distance between the machine and nearby objects should be 30cm. Good ventilation is of critical importance
to the normal performance and lifespan of the machine.
2) Over-load is forbidden
The welder is operated according to allowable duty circle (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.,
Please refer to "Technical Parameters" for the power supply voltage range. This machine is of automatic
voltage compensation to ensure the welding current is within the given range. In case that the input voltage
exceeds the stipulated value, it would possibly damage the components of the machine. The operator should
take according measures to this case.
4) A sudden halt may occur with the front panel's yellow indicator lighting up while the machine is of over-load
status. Under this circumstance, it is unnecessary to restart the machine for it's resulted from over heating
and the triggered the temperature control switch. Keep the built-in fans working to lower the machine's
temperature. Welding can be resumed when temperature falls into the standard range and the yellow
indicator is off.
