TECHNICAL DESCRIPTION
1.1
DESCRIPTION
The wire feeder together with a generator form an installation that
can be used on the direct wire welding process. Linked to gener-
ators it is able to satisfy many operative requirements.
The self-regulation of the wire speed covers three to four position
variations of the work tension. This facilitates the welding param-
eters regulation. Furthermore, it continuously adapts the advance
wire speed to the grid tension and the arcs length variations.

* For using the entire range of wires possible, the wire rollers sup-
plied must be supplemented with those having suitable grooves
(e.g. Knurled grooves for cored wires)
** The shielding gas used depends on the metal being welded;

CONNECTION TO THE GENERATOR
1.
Make sure the generator is off before carrying out this operation.
2.
Connect the umbilical cord's power socket to the relative plug
placed at the back panel of the machine (insert it completely
and rotate clockwise so that it is completely blocked).
3.
Connect the multiple plugs to the relative socket blocking it
with the appropriate end.
4.
Connect the gas tube coming out from the cord to the cylinder
pressure reducer.

WIRE REEL INSTALLATION
3.1
WIRE REEL INSTALLATION
1.
Put the wire reel in the relative spool so that the two rotate to-
gether.
2.
Adjust the spool brake by means of the central nut on the lat-
ter, so that the reel rotates easily (on some spools the adjust-
ment nut is not visible, but is accessible after withdrawing the
retainer tab).
3.
Open the upper bridge of the wire feed unit
4.
Check that the rollers are suited to the diameter of the wire to
be used; otherwise change.
5.
Straighten an end section of the wire and cut it.
6.
Pass the wire over the two lower rollers and insert in the torch
connector tube until it protrudes from the latter by approx. 10 cm.
7.
Close the upper bridge of the wire feed unit and check that
the wire is positioned in the relative groove.
8.
Connect the torch and insert the protruding wire section into
the sleeve, taking care that the control pins are fitted correctly
in the seats and the connector nut is tightened fully down.

START-UP
1.
Switch on the machine
2.
Set the power switch to an intermediate position.
3.
Remove the nozzle and wire guide tube from the torch, press
the button and feed the wire until it protrudes from the front
section of the torch. While feeding wire through the torch, use
the handwheel to adjust the force that the wire pressure roller
exerts on the feed roller; the setting must ensure that the
welding wire moves regularly without slipping on the rollers
and without deforming. Fit the torch with a suitable wire guide
tube according to the type of wire used.
4.
Secure the wire guide tube, and ensure that the diameter cor-
responds to the wire used.
WELDING WIRE CAN CAUSE INJURY.
Never point the torch towards the body or towards
other metals when unwinding welding wire.
5.
Refit the gas nozzle.
6.
Open the gas cylinder valve.
7.
Connect the ground clamp to the workpiece on a section free
of rust, paint, grease or plastic.
IMPORTANT: IF THE WIRE FEEDER IS SUSPENDED DURING
WELDING, MAKE SURE THE WIRE FEEDER FRAME IS ISO-
LATED FROM THE EARTHING CIRCUIT (E.G. USE LIFTING
ROPES IN NYLON OR OTHER INSULATING MATERIAL).
THIS PRECAUTION IS INDISPENSABLE IN ORDER TO PRE-
VENT POSSIBLE RECLOSURE OF THE WELDING CURRENT
THROUGH THE LIFTING MEANS AND THE ELECTRICAL
SYSTEM EARTHING CIRCUIT.
FAILURE TO COMPLY WITH THIS SAFETY RULE CAN RE-
SULT IN SERIOUS DAMAGE TO THE ELECTRICAL SYSTEM
AND COMPROMISE THE TROLLEY LIFTING SYSTEM.
