Introduction

Thank you for buying our product.
In order to get the best performance out of the plant and ensure the
maximum lifespan of its parts, the use and maintenance instruc­tions contained in this manual must be read and strictly complied
with, as well as the safety instructions contained in the rele-
vant folder. If repairs to the plant are required, we recommend that
our clients contact our service centre workshops, as they have the
necessary equipment and personnel that are specifically trained
and constantly updated.
All our machines and equipment are constantly developed and so
changes may be made in terms of their construction and features.

IMPORTANT: T he wire feeder must only be used together with the
welding power source and not for any other use.

Description

Professional large diameter 4-roller wire feeder that guarantees
precise and constant feeding of the wire. This wire feeder’s prin­cipal characteristics are:

• Designed for use with all types of solid and core type wire.

• A 24 V direct current ratio motor, fitted with an encoder.

• A gas solenoid valve.

• Wire speed (welding current) and welding voltage adjustment.

• Gas and wire feed test.

Graduated knobs for precise adjustment of the wire pressure

•

that stays unvaried when the arms open and close.
The wire feeder rollers can be replaced without using any tools.

•

How to lift up the system

The wire feeder is fitted with a strong handle, built into the frame,
which is only used to facilitate lifting and carrying it.

NOTE: The lifting and transporting devices conform with Europe­an regulations. Do not use other equipment to lift or transport the
wire feeder.

Opening the packaging

When receiving the wire feeder remove it and all its accessories /
components from the relevant packing, and check that they are in
good condition. If not, report the situation to the dealer immediately .

Installation and connections

CONNECTION OF THE INTERCONNECTING CABLE
BETWEEN WIRE FEEDER AND WELDING POWER
SOURCE

The extension between the welding power source and wire feed­er consists of a power cable, a multipolar cable for auxiliary pow­er supply and a gas hose which are to be connected to the rear
of the wire feeder.

The gas tube must be connected to the quickfit connector

•

(Pos. 5, Fig. A).

•

The power cable must be fixed to the quick-fit connector (Pos. 7,
Fig. A).

•

The auxiliary cable must be fixed to the special connector
(Pos. 6, Fig. A).

2

The connecting cable also includes the feed (blue) and return (red)
pipes for the water that are used for cooling the welding equip­ment’s torch that must be connected to the respective (blue and
red) rapid couplings on the back of the wire feeder (Pos. 3, Fig. A).
Once this task has been completed, do not forget to secure the
connecting cable to the base, using the special little strap provided.

CONNECTING THE TORCH

Screw the torch onto the centralised connection on the front panel
of the wire feeder (pos. 4, Fig. A) and connect the feed (blue) and
return (red) water hoses for cooling the torch head to the respec­tive (blue and red) rapid couplings on the front panel of the wire
feeder (Pos. 3, Fig. A).

Loading wire

•

Insert the spool (Ø 300 mm max.) onto its support so that the
wire unwinds anticlockwise and centre up the protruding ref­erence point on the support with the respective opening in the
spool.
Thread the end of the wire into the back guide (Pos. 1, Fig. B)

•

on the drawing mechanism.
Lift up the idle rolls (Pos. 4, Fig. B) releasing the roll pressure

•

device (Pos. 2, Fig. B). Make sure that the drive rolls (Pos. 7,
Fig. B) have the diameter corresponding to the wire being used
stamped on the outside.

• Insert the wire into the central wire guide and the wire guide on
the centralised connection (Pos. 5, Fig. B) by a few centimetres.
Lower the idle roller holder arms, making sure that the wire slots
into the hollow in the motor’s roller. If necessary , adjust the pres ­sure between the rollers by turning the relevant screw (Pos. 2,
Fig. B). The correct pressure is the minimum that does not allow
the rollers to skid on the wire. Excessive pressure will case de­formation of the wire and tangling on the entrance of the sheath;
insufficient pressure can cause irregular welding.

Assembly of drive rolls

Unscrew the two screws (Pos. 6, Fig. B). Lift up the idle rollholder
arm (Pos. 3, Fig. B) and proceed as follows:

• Each roller shows the type of wire and diameter on the two ex­ternal sides.
Install the right rolls (Pos. 7, Fig. B) making sure the groove is

•

in the correct position for the diameter of the wire being used.

Before welding

•

Before welding, check that the data on the welding power source
plate correspond to the supply voltage and frequency.
Make sure that the wire feeder is correctly connected to the pow-

•

er source through the interconnecting cable and that the ground
cable is connected to the piece to be welded.
