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 automatically.
However, excessive use (e.g. too high voltage) of machine may also damage
machine, so please note:
2.1 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 12".
Good ventilation is of critical importance for the normal performance and
lifespan of the machine.
2.2 Welding operation is forbidden while the machine is overloaded.
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.
2.3 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.
2.4 A sudden halt may occur while the machine is of overload status. Under
this circumstance, it is unnecessary to restart the machine. Remain the
built-in fan working to lower the temperature inside the machine.
