wire feeder use the interconnection cables provided.
• Place the power source in a well ventilated area: dust, grit or any other thing that may obstruct the
air intake and output vents can prevent the ventilation and good operation of the welder.
4.2 TORCH LEAD ASSEBLY – EURO
CONNECTION (fIG.4)
• Plug the torch hose into the socket on the front of the
welder and secure by hand screwing in the threaded
connection.
4.3 TORCH LEAD ASSEMBLY – DIRECT CONNECTION (fIG. 5)
• Before fitting the torch hose assembly (7) on the machine remove the nut (1) and the washer (2). Then,
measure the length of the liner from the brass nut (10). This measurement should be a maximum of
20mm, and should be carefully trimmed to this length using a good pair of side cutters, or similar,
ensuring there are no burrs or sharp edges which may impede the progress of the wire when fitted.
• Carefully feed the hose assembly (7) through the hole in the front face of the welder, taking care to
feed the electrical connector (14) through at the same time. Then connect them to the wire feeder.
Then insert also the threaded terminal ring (3), the power cable terminal, the washer (2) and screw
on the nut (1) tightly.
• Fit the plastic cover (15) over the bracket assembly (4) securing with the two self-tapping screws
provided.
• Connect the gas hose (12) to the gas hose nipple (6) securing with the hose clamps supplied (13).
• Make the electrical connec-
tions by joining connectors
(11-14)
Note: when correctly
assembled the wire liner
(9) must be at 2-3 mm
distance from the point
of contact between the
upper and lower roll.

5.0 COOLINg UNIT AND INTERCONNECTION CAbLE

Water cooling unit is a device used to cool the welding torch, if required by the welding you are perfor-
ming. Using a pump, a water recirculation system between the torch and the cooling unit is created.
5.1

ASSEMBLY

Fix the cooling unit support to the generator upper panel, place the cooling unit on the support and fix
it. Then, fasten the wire feeder rotating support to the cooling unit cover. (see Fig. 6)
These connections must be done by qualified workers, making sure that the generator is
not connected to the mains.
5.2

CONNECTIONS

• Remove the right top panel of generator: next to the generator rear there is a terminal board to
which the cooling unit must be connected.
