The wire adapter shown in Figure 2.2-b is opened by turning it. The welding
wire reel is placed in the wire feeder unit of the welding machine with the wire
coming from below and the adapter is tightened again.
Gas Button (Figure 2.2-c): During gas cylinder replacement or gas related
connections, the gas valve can be opened by pressing this button. Thus, it can
be checked whether the gas is coming smoothly or not.
Wire Feeding Button (Figure 2.2-d): This button is used to ensure that the wire
feeder motor rotates during the insertion of the welding wire. When the wire
is finished, the wire should be driven by pressing this button until the wire
comes out of the tip of the torch after the new wire is inserted.
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
connections (Figure 2.1-a). The phase order is
not important, thus, connect the three phase
cables to the phase supply of the utility.
