meet the welding requirements;
2.4.
The in-time protection circuit provides signals to the PWM warning for overheat
and over-current situations;
2.5.
The closed-loop control method is adopted to make the welding power source
have good anti-grid fluctuation ability and excellent welding performance.
Installation and Wiring
1.
Location Requirements
1.1. The machine should not be installed in an area where it is exposed to direct
sunlight or rain but where the humidity is as low as possible and the ambient
temperature is within the range of -10 °C - 40 °C.
1.2. The machine should be installed on a flat, preferable level surface but, in any
case not on a surface with an inclination of more than 10 degrees.
1.3. The machine should not be operated in a work station exposed to wind. Should
a windy environment be unavoidable, suitable screening should be installed.
1.4. In order to allow for efficient ventilation, a clear space of at least 20cm should be
allowed in front of and behind the machine as well as at least 10cm at each
side.
2.
Power Input Requirements
The power supply waveform should be the standard sin wave, the rated voltage
380V±10% 50/60Hz. Three phase voltage unbalance should be
≤
5
%.
