6. NOTES OR PREVENTIVE MEASURES
ENVIRONMENT
1. The machine should be operated in dry environments with humidity levels of max 90%.
2. Ambient temperature should be between -10 to 40 degrees centigrade.
3. Avoid welding in sunshine or drippings. Do not let water infiter the machine.
4. Avoid welding in dust area or the environment with corrosive gas.
5. Avoid gas welding in the environment with strong airflow.
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.
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 inner- 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 keeps in allowable range. If power voltage is exceeding 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 because of electricity 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.
