The welding wire is stretched from the 1st guide shown in Figure 2.5 and driven
onto the wire reel. The wire passed through the guide is inserted into the wire
drive reel channel as shown in Figure 2.5-2. The wire passed through the reels
is passed through the direction guide as in Figure 2.5-3, and the manual driving
process is completed. After the manual driving process is completed, overprints
are closed(Figure 2.4-4). By pressing the wire feed button, the wire is fed until
the wire comes out homogeneously from the tip of the torch.
If the pressure setting is too high, crushing may occur on the
wire. The round structure of the wire may be disrupted and
problems may occur while passing through the torch. In
addition, the problem of clogging in the contact nozzle may be
encountered. If the pressure is low, the wire will be loose and
the wire feeding will not be homogeneous. When adjusting the
pressure, it is done from loose to tight.
2.3. GAS CONNECTION
Argon or Argon + Helium is used for welding aluminum, magnesium, copper and
their alloys of non-ferrous metals, and Argon + Oxygen mixed gases are used for
welding stainless steels.
The oxygen ratio must never exceed 3% in welding stainless steels .
Attach the gas connection hose and regulator to the tube, loosen the
adjustment screw and turn on the gas and adjust the gas flow by tightening the
adjustment screw. If CO2 gas is to be used, a CO2 heater should be connected.
There is a power plug for the CO
2
heater at the rear of the welding power unit
(Figure 1.2-b).
WARNING : The 220 Volt 120-Watt socket located at the back
of the machine is only for the heater. Do not use it for other
purposes. It can damage the machine.
