After having changed the supply voltage, re-place the upper cover.
This machine must never be used without the top and side covers. This is both for obvious safety reasons
and to avoid interference with the machine’s internal cooling system. The warranty is to be considered null
and void it this machine is used without the protection of its top and side covers.
Mount a plug on the power supply cable that corresponds to the input power drawn by the machine.
4.3.1 Wire feeder connection
This power source is compatible with the wire feeders. To connect the power source to the wire feeder units
use the extension art. Performances and operating features of the wire feeder are described in the
operating manuals supplied with the wire feeder itself.
4.3.2 Connecting the work return lead clamp.
Some versions have one impedance socket only.
Connect the male end of the work return lead to one of the impedance taps on the front panel of the
machine. The impedance tap designated by the provides the maximum amount of impedance which
will produce nicely filleted weld beads. This tap is recommended when welding aluminium, stainless steel,
and carbon steels of binary or ternary composition. The impedance tap designated by the provides the
least amount of impedance and is recommended when using carbon dioxide as a shielding gas to weld
carbon steels, in the upwards vertical position, of binary or ternary composition.
It is generally advisable to use low impedance values for small diameter wires and high values for big
diameter wires.
After having selected the proper impedance tap, attach the work return clamp to the work to be welded.
Make sure that the ground clamp is tightly fastened to the work return cable and periodically check that
this connection remains well tightened. A loose connection can cause weld current drops or overheating of
the work return lead and clamp which, in turn, creates the risk of burns from accidental contact with the
work return lead. The weld circuit must not be placed deliberately in direct or indirect contact with the
ground conductor if it is not in the work to be welded.
If the work to be welded is attached deliberately to the ground by a protection lead, then the connection
must be the most direct possible and it must be done using a lead that has a cross section that is at least
equal to the cross section of the work return lead being used for the weld circuit. The protection lead must
also be attached to the work at the same spot as the work return lead. To do so, a second ground clamp,
fitted to the protection lead, must be attached next to the ground clamp of the work return lead.
4.3.3 Connecting the gas hose.
Keep the cylinders in an upright position by chaining them to their support.
Keep the cylinders in a place where they cannot be damaged.
Do not lift the machine with the cylinder on its support.
Keep the cylinder away from the welding area and uninsulated electric circuits.
Cylinders containing inert gas have to be equipped with a pressure reducer and a flowmeter.
After having positioned the cylinder, connect the gas hose that comes out from the rear of machine to the
pressure reducer output.
Regulate the gas flow to 8-10 L/min.
4.4.1 INSTALLATION AND STARTER
Machine installation must be done by a competent staff. All connections must correspond to the rules in
