supply. Table 1 (TAB.1) shows the recommended delayed fuse
size in amps, chosen according to the max nominal current
supplied by the welding machine, and the nominal voltage of the
main power supply.
Reassemble the panel carefully using the appropriate screws.
WARNING!
Failure to observe the above rules will make the (Class 1) safety system installed by the manufacturer
ineffective with consequent serious risks to persons (e.g. electric shock) and objects (e.g. fire).
CONNECTION
OF
THE
WELDING
CABLES:
Table 1 (TAB. 1) gives the recommended values for the
welding cables depending on the maximum current supplied
by the welding machine.
WARNING! BEFORE MAKING CONNECTIONS MAKE SURE THE WELDING MACHINE IS SWITCHED OFF AND
DISCONNECTED FROM THE POWER SUPPLY OUTLET.
-
A gas bottle can be loaded on the welding machine
bottle support platform: max 20kg.
CONNECTION TO THE GAS BOTTLE:
-
Screw the pressure reducing valve on to the gas bottle
valve, inserting the appropriate adapter for argon or an
argon/C02 mixture.
-
Connect the gas inlet pipe to the pressure-reducing
valve and tighten the band supplied.
-
Loosen the pressure adjustment knob nut on the
pressure-reducing valve before opening the bottle
valve.
CONNECTING THE WELDING CURRENT
RETURN CABLE:
-
This is connected to the piece being welded or to the
metal bench supporting it, as close as possible to the
join being made. This cable is connected to the terminal
with the symbol (-).
CONNECTING THE TORCH (ONLY FOR
VERSIONS WITH EURO CONNECTOR):
-
Engage the torch with its dedicated connector by
tightening the locking ring manually as far down as it
will go. Prepare the wire for loading by dismantling the
nozzles and the welding tip to ease its exit.
CHANGING THE POLARITY (ONLY FOR GAS-NO GAS VERSIONS)
Step 1: Open the reel compartment door.
Step 2a: MIG/MAG Welding (gas)
Or Step 2b: Flux Welding (no gas)
Connect the torch cable from the wire to
the terminal (+)
Connect the clamp return to the terminal (-)
Connect the torch cable from the wire feeder to
the terminal (-)
Connect the clamp return cable to the terminal (+)
