） Do not over load
！
The operator should remember to watch the max duty current (Response to the selected duty
cycle). Welding current should 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 keeps is in allowable range. If power voltage is
exceeding allowable range limits, it can damage the components of machine. The operator should
understand this situation and take preventive measures.
4
） There is a grounding screw behind welding machine, with a grounding marker on it. Before
operation, welding crust must be grounded reliably with cable which section is over 6 square
millimeter, in order to prevent from static electricity, and accidents because of electricity leaking.
5
） If welding time is exceeding 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, 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.
