4. NOTES OR PREVENTIVE MEASURES
1. Environment
1. The machine can perform in environment where conditions are dry with a
dampness level of max 90%.
2. Ambient temperature is between -10 to 40 degrees centigrade.
3. Avoid welding in sunshine or drippings. Do not let water enter the gas.
4. Avoid welding in dust area or the environment with corrosive gas.
5. Avoid gas welding in the environment with strong air fl ow.
2. Safety norms
Our welding machine has installed protection circuit of over voltage, over current
and over heat. When voltage, 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 to fol-
lowing.
1. The working area is adequately ventilated.
Our welding machine is powerful machine, when it is being operated, it gener-
ated by high currents, and natural wind can’t be satis fi ed with 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 ma-
chine.
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 allow-
able range. If power voltage is exceeding allowable range limited, it is dam-
aged to components of machine. The operator should understand this situation
and take preventive measures.
4. 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 -E2 Error Code will be shown on digital display.
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.
