INSTRUCTION MANUAL
CAREFUL:
READ THE INSTRUCTION MANUAL CAREFULLY BEFORE
USING THE WIRE FEEDER.
1. GENERAL SAFETY FOR ARC WELDING
Scrupulously follow the safety instructions given in the
generator manual.
The guards and mobile parts of the wire feeder casing
must be in position before connecting the welding machine to
the power supply.
CAREFUL! Any manual intervention on moving parts of
the wire feeder, such as, for example:
- Replacing the feeder and/or wire guide;
- Inserting the wire into the feeders;
- Loading the reel of wire;
- Cleaning the feeders, gears and the area below them;
- Lubricating the gears.
MUST BE CARRIED OUT WITH THE WELDING MACHINE OFF
AND DISCONNECTED FROM THE MAINS.
- Do not use the handle to hang the welding machine.
2. INTRODUCTION AND GENERAL DESCRIPTION
WIRE FEEDER
This wire feeder must be connected to an electric generator that
has been suitably configured to run MIG-MAG short and spray arc
welding.
Its specific characteristics, such as the precision of the wire speed
adjustment and the regular feeding of the 4-roll wire feeder unit
make it particularly suitable for MAG welding carbon steel or low-
alloy steel with CO protective gas or Argon/CO
2
cored (tubular) electrodes. It is also ideal for MIG welding stainless
steel with Argon gas containing 1-2% oxygen, and aluminium with
Argon gas, using electrode wires for analyses that are suitable for
the workpiece to be welded.
Perfect also for MIG soldering galvanized plates with copper alloy
wires (e.g. copper-silicone or copper-aluminium) with pure Argon
protective gas (99.9%).
3. TECHNICAL DATA
3.1 DATA PLATE
The main data regarding wire feeder use and performance are given
in the data plate and have the following meaning:
1- EUROPEAN reference standard for wire feeder safety and
production.
2- Power supply line symbol.
3- Casing protection rating.
4- Welding circuit performance:
- I : Nominal welding current
2
- X: Intermittence ratio: indicates the time during which the
welding machine can supply the corresponding current.
It is expressed as a % on the basis of a 10 min. cycle (e.g. 60%
= 6 working minutes, 4 pause minutes and so on).
5- Power supply line characteristic data;
- U : Wire feeder alternate power supply voltage.
1
- I : Nominal current at maximum wire feeder charge.
1
6- Serial number for identifying the wire feeder (essential for
technical help, when requesting spare parts, product origin
search).
7- Symbols referring to safety regulations, the meaning of which is
given in chapter 1 "General safety for arc welding".
Note: The example plate shown indicates the meaning of the symbols
and numbers; the exact values of the welding machine technical data
in your possession must be identified directly on the welding machine
plate.
The main data regarding wire feeder use and performance are given
in table 1 (Tab.1).

5. INSTALLATION

CAREFUL! CARRY OUT ALL INSTALLATION AND
ELECTRICAL CONNECTION OPERATIONS WITH THE WELDING
MACHINE RIGOROUSLY SWITCHED OFF AND DISCONNECTED
FROM THE MAINS.
THE ELECTRICAL CONNECTIONS MUST ONLY BE CARRIED
OUT BY EXPERT OR QUALIFIED TECHNICIANS.
PREPARATION
Unpack the wire feeder.
CONNECTION TO THE POWER NETWORK
When connecting to the power network scrupulously follow the
indications given in the generator manual.
WELDING CIRCUIT CONNECTIONS (FIG. C)
ATTENTION!
FOLLOWING CONNECTIONS, MAKE SURE THE WELDING
MACHINE IS OFF AND DISCONNECTED FROM THE MAINS.
Connecting the welding current return cable
Connect the cable to the piece to be welded or the metal bench on
which the workpiece is placed, as close as possible to the joint being
worked.
Connect this cable to the clamp with the symbol (-).
Connecting the torch
- Insert the torch into the dedicated connector, fully tightening the
locking ring nut manually. Prepare the torch to receive the wire for
the first time, removing the nozzle and the contact pipe, to make
exiting easier.
- Connect the water pipes to the quick couplings (for R.A. version
only).
CONNECTING THE WIRE FEEDER
- Connect to the current generator:
- welding current cable to the quick coupling (+);
- control cable to the relative 14-pole connector.
- Make sure the connectors are well tightened to avoid overheating
and loss of efficiency.
- Connect the gas hose coming from the wire feeder to the cylinder
pressure reducing valve and tighten with the supplied strip.
- Connect the water pipes coming from the wire feeder to the quick
couplings on the cooling unit (for R.A. version only).
CONNECTING G.R.A. TO THE MAINS NETWORK (for R.A.
version only)
- Before making any electrical connections, make sure the rating
data of the cooling unit corresponds to the mains voltage and
frequency available at the place of installation.
- The cooling unit must only be connected to a power supply system
with neutral conductor connected to earth.
- Connect the supplied cable to the cooling unit (FIG. l), using the
relative coupling (female 5-pole). Connect the free end of the
cable to a normalised plug (2P + E); the relative earth lug must
be connected to the power supply protective ground wire (yellow-
green).
Both the plug and socket must have the rated voltage and current
requirements.
