7. PRECAUTIONS
1) Environment
① The machine should be operated in dry environments with humidity level of max 90%.
② Ambient temperature should be between -10 to 40 degree centigrade.
③ Avoid welding in sunshine or drippings. Do not let water infilter the machine.
④ Avoid welding in dusty area or the environment with corrosive gas.
2) Safety norms
The welding machine is installed with protection circuit of over voltage, over current and over
heat. When voltage, output current and temperature of machine exceed the required standard, welding
machine will stop working automatically. However, overuse (such as over voltage) will still result in
damage to the welding machine. To avoid this, the user must pay attention to the following notes.
① The working area is adequately ventilated!
The welding machine is powerful machine.When it is being operated, it generated by high current,
under this situation,natural wind will not satisfy machine cool demands. So a fan is used into
inner-machine to cool down itself. Make sure the intake is not blocked or covered.The objects around
the welding machine should be kept away not less than 0.3 meters.Make sure the working area
adequately ventilated is specially necessary. It is vitally important for the performance and 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 Do not over voltage!
Power voltage can be found in diagram of main technical data. Automatic compensation circuit of
voltage will assure the welding current keep in allowable range. If power voltage exceeds the allowable
range limited, it will damage to 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 reliable with cable which section is over 6 square
millimeter, in order to prevent from static electricity , and accidents possibly caused by electricity
leaking.
⑤ If welding time exceeds the 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 yellow (red). In this situation, you needn't pull the plug, in order to let the fan cool the
