Environment
1
）
The machine can perform in environment where conditions are dry with a dampness lever of max
90%.
2
）
Ambient temperature is between 10 to 40 degrees centigrade.
3
）
Avoid welding in sunshine or drippings.
4
）
Do not use the machine in environment where condition is polluted with conductive dust on the air
or corrosiveness gas on the air.
5
）
Avoid gas welding in the environment of strong airflow.

Safety norms
The welding machine has installed protection circuit of over voltage and current and heat. When
voltage and output current and temperature of machine are exceeding the rate standard, welding
machine will stop working automatically. Because that will be damage to welding machine, user
must pay attention as following.
1
）
The working area is adequately ventilated
！
The welding machine is powerful machine, when it is being operated, it generated by high currents,
and natural wind will not satisfy machine cool demands. So there is a fan in inter-machine to cool
down machine. Make sure the intake is not in block or covered, it is 0.3 meter from welding machine
to objects of environment. User should make sure the working area is adequately ventilated. It is
important for the performance and the longevity of the machine.
2
）
Do not over load
！
The operator should remember to watch the max duty current (Response to the selected duty cycle).
Keep welding current is not exceed max duty cycle current.
Over-load current will damage and burn up machine.
3
）
No over voltage
！
Power voltage can be found in diagram of main technical data. Automatic compensation circuit of
voltage will assure that welding current keep in allowable arrangement. If power voltage is
exceeding allowance arrangement limited, it is damaged to components of machine. The operator
should understand the situation and take preventive measures.
4
）
There is a grounding screw behind welding machine, there is grounding marker on it Mantle must
be grounded reliable with cable which section is over 6 square millimeter I order to prevent from
static electricity and leaking.
5
）
If welding time is exceeded duty cycle limited, welding machine will stop working
for protection. Because machine is overheated, temperature control switch is on
“ON’’ position and the indicator light is red. In this situation, you don’t have to
pull the plug, in order to let the fan cool the machine. When the indicator light is
off, and the temperature goes down to the standard range, it can weld again.
