1. Mini Circuit Braker
- The function of Mini Circuit Braker is to protect welding machine by automatic trip to
turn-off power supply while in machine overload or failure. Normally, the switch flipped
to upward which means power-on. Use switch on the disconnected switchboard or
switchbox(customers prepare by themselves) to start or stop welding machine, avoid-
ing using the Mini Circuit Braker.
2. Gas Heater power cable socket AC36V
- Wire to CO regulator’s heater coil
3. Cooling fan (Axial flow fan)
- Cool down the heat components in the welding machine.
Note:
The fan will rotate when welding, but will not rotate only after power on. The fan will
halt rotating automatically after stop welding in fifteen minutes.
4. Input power cable
- The mixed-colored wire must be firmly grounded, the rest wires connect to 3-phase
power (380v/50Hz) respectively.
5. Ground bolt
- To ensure operators not to be harmed and welding machine to be working normally,
make sure the ground bolt grounded firmly by ground lead specified in the table 1-4, or
ground wire(mixed-colored) of the input power cord grounded firmly.
