1.1 Working Environment
1) The installation should be performed in place which can withstand the weight of the welding machine.
2) Installation should not be performed in place where water splash may happen such as water pipe.
3) Welding should be carried out in dry environment with humidity of 90% or less.
4) The temperature of the working environment should be between -10℃ and 40℃.
5) Welding should not be performed in sunlight or rain. Keep it dry at all times.
6) Welding should not be performed in dusty area or environment with corrosive chemical gas.
7) Gas shielded arc welding should be operated in environment without strong airflow.
8) Welding should not be performed on a platform with slope of more than 10°.
9) A breaker over 50A is recommended.
1.2 Safety Tips
Over-current and over-heating protection circuit are installed in this machine. When the output current
and inner temperature exceeds the set standard, the machine will stop automatically. However,
excessive use will cause damage to the welder. Therefore, please note:
1) Make sure good ventilation.
This welder can create powerful welding current that has strict cooling requirements that cannot be
met with natural ventilation. Therefore the internal fan is very important in enabling the machine to work
steadily with effective cooling. 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) Overload is forbidden.
Welder should be operated according to allowable duty cycle (refer to the duty cycle table). Make
sure that the welding current should not exceed the max load current. Overload could obviously shorten
the machine's service life, or even damage the machine.
3) Over-voltage is forbidden.
Regarding the power voltage, please refer to “Technical Parameters” table. This machine is of
automatic voltage compensation, which ensures welding current is within allowable range. In case that
the power voltage exceeds the allowable value, it would damage the machine. Operators should be fully
aware of such situation and take according precautions.
4) The power cord of a welder has a yellow/green ground cable.
Before operation, well connect the ground cable to GND to discharge static electricity or prevent
accidents caused by static electricity. A sudden halt may occur with digital display showing “E60” on the
front panel if the machine is in over-load triggering temperature switch. Under this circumstance, it is
unnecessary to unplug the power plug so that the fan keeps working to cool down the machine. Welding
can be continued after the inner temperature falls into the standard range and “E60” is off.
