Welding cable coupling device, negative pole:
Connects to electrode
holder cable set in DC electrode negative mode. Connects to earth clamp
cable set in DC current electrode positive mode.
Working Principle
1.
Diagram Explaining Working Principle
1.1. A bridge rectifier converts AC to DC;
1.2. After secondary rectification and reactor filtering, output welding current is
delivered that meets the welding requirements;
1.3. Controlled by PWM the IGBT inverts the DC to 20KHz AC which is transmitted
via a high-frequency transformer;
1.4. The in-time protection circuit provides signals to the PWM warning for overheat
and over-current situations;
1.5. A closed-loop control system ensures a good anti-grid fluctuation ability and an
excellent cutting 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°.
