Preset the welding current according to the type and size of the electrode, clip the
electrode and then welding can be carried out by short circuit arc starting. For welding
parameters, please refer to 6.3.

materials and welding process for reference.
7. CAUTION
1. 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 -1
0
℃
to 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) Gas shielded arc welding should be operated in environment without strong airflow.
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 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.
2.2 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.
2.3 Over-voltage is forbidden.
Regarding the power supply voltage range of the machine, please refer to
