3.1 START-UP. PRELIMINARY OPERATIONS.
In principle, the system must be connected as indicated in the previous chapter and before starting the
system up definitely, the following steps must be taken:
1) Make sure the mains voltage is the same as that pre-selected in the machine.
2) Connect supply cable K to the relative three-phase outlet.
3) Check that the gas bottle is well protected by the bottle-holder system, and above all, check that the
safety chain is properly placed.
4) Install the pressure-reducing valve F and connect gas hose E checking that there are no leakages,
throughout the whole circuit.
5) Fit the relative adapter onto the wire reel and fit this assembly into the wire reel support axle. Please
carefully read the wire-feed unit instructions manual.
6) Depending on the wire diameter, fit the groove of the correct driving roller.
7) Fit the wire into the driving system. Do not force the wire pressure handle, as if this is too tight, the motor
remains on overload and does not reach the maximum speed, and if the handle is too slack, the wire
could slip. Once the wire has been fitted, we can then hook up the G torch.
8) Fit earth connector J into earth tap H. After this you can connect the equipment with the on switch to start
the welding process.
