2.2. WELDING POWER SUPPLY TO WIRE FEEDER CONNECTION

Figure 3.1. Welding power
supply rear view
Welder power supply works with three phase 380 Volt
50Hz utility power. The energy input cable is located at
the rear of the welder power supply. The yellow-green
cable (Figure 2.1-PE) should be connected to protective
earth. The remaining cables are the three phase
connections (Figure 2.1-a). The phase order is not
important, thus, connect the three phase cables to the
phase supply of the utility.
The welding power supply provides (Figure 3.1) water cooling
heat exchange and pressure pump (Figure 3.1-c), welding
current (Figure 3.1-d) and supply current to the wire feeder
(Figure 3.1-d). The connection between these two units is
made by provided extension cable with welding cable, trigger
cable, pressured water inlet and outlet hoses packed in a
flexible hose.
