WARNING!
Wire feeders are intended to be used with power sources in MIG/MAG mode
only.
If used in any other welding mode, such as MMA, the welding cable between wire
feeder and power source must be disconnected, or else the wire feeder becomes
live or energized.
WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
• Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing
• Insulate yourself from work and ground.
• Ensure your working position is safe
ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health
• Welders having pacemakers should consult their physician before welding.
EMF may interfere with some pacemakers.
• Exposure to EMF may have other health effects which are unknown.
• Welders should use the following procedures to minimize exposure to
EMF:
○ Route the electrode and work cables together on the same side of
your body. Secure them with tape when possible. Do not place your
body between the torch and work cables. Never coil the torch or
work cable around your body. Keep welding power source and
cables as far away from your body as possible.
○ Connect the work cable to the workpiece as close as possible to the
area being welded.
FUMES AND GASES - Can be dangerous to health
• Keep your head out of the fumes
• Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area

1 SAFETY
0459 936 301 -6- © ESAB AB 2017
ARC RAYS - Can injure eyes and burn skin
• Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing
• Protect bystanders with suitable screens or curtains
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
MOVING PARTS - Can cause injuries
• Keep all doors, panels and covers closed and securely in place. Have only
qualified people remove covers for maintenance and troubleshooting as
necessary. Reinstall panels or covers and close doors when service is
finished and before starting engine.
• Stop engine before installing or connecting unit.
• Keep hands, hair, loose clothing and tools away from moving parts.
FIRE HAZARD
• Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby
• Do not use on closed containers.
MALFUNCTION - Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
CAUTION!
This product is solely intended for arc welding.
CAUTION!
Class A equipment is not intended for use in residential
locations where the electrical power is provided by the
public low-voltage supply system. There may be potential
difficulties in ensuring electromagnetic compatibility of class
A equipment in those locations, due to conducted as well
as radiated disturbances.
NOTE!
Dispose of electronic equipment at the recycling
facility!
In observance of European Directive 2012/19/EC on Waste
Electrical and Electronic Equipment and its implementation
in accordance with national law, electrical and/or electronic
equipment that has reached the end of its life must be

5.3 Setting the wire feed pressure
Illustration A Illustration B
Start by making sure that the wire moves smoothly through the wire guide. Then set the
pressure of the wire feeder's pressure rollers. It is important that the pressure is not too
high.
To check that the feed pressure is set correctly, you can feed out the wire against an
insulated object, e.g. a piece of wood.
When you hold the welding torch approximately 6mm (¼in.) from the piece of wood
(illustration A), the feed rollers should slip.
If you hold the welding torch approximately 50 mm (2in.) from the piece of wood, the wire
should be fed out and bend (Illustration B).
5.4 Replacing and inserting wire
• Open the side panel.
• Disconnect the pressure sensor by folding it backwards, the pressure rollers slide up.
• Straighten out the new wire 10-20 cm. File away burrs and sharp edges from the end
of the wire before inserting it into the wire feed unit.
• Make sure that the wire goes properly into the feed roller's track and into the outflow
nozzle or wire guide.
• Secure the pressure sensor.
• Close the side panel.
5.5 Changing feed rollers
• Open the side panel.
• Disconnect the pressure sensor (1) by folding it
backwards, the pressure rollers slide up.
• Disconnect the pressure rollers (2) by turning the
axle (3) 1/4 turn clockwise and pulling out the axle.
The pressure rollers disconnect.
• Disconnect the feed rollers (4) by unscrewing the
nuts (5) and pulling out the rollers.
During installation, repeat the above in reverse order.
Choice of track in the feed rollers
Turn the feed roller with the dimensioning mark for the required track towards you.

6 MAINTENANCE
0459 936 301 - 15 - © ESAB AB 2017
6 MAINTENANCE
NOTE!
Regular maintenance is important for safe and reliable operation.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer
attempts any work to rectify any faults in the product during the warranty period.
6.1 Inspection and cleaning
Wire feed unit
Check regularly that the wire feed unit is not clogged with dirt.
• Cleaning and replacement of the wire feed unit mechanism's worn parts should take
place at regular intervals in order to achieve trouble-free wire feed. Note that if
pre-tensioning is set too hard, this can result in abnormal wear on the pressure roller,
feed roller and wire guide.
The brake hub
The hub is adjusted when delivered.
• Adjust the brake hub so that wire is slightly slack
when wire feed stops.
Welding torch
• The welding torch's wear parts should be cleaned and replaced at regular intervals in
order to achieve trouble-free wire feed. Blow the wire guide clean regularly and clean
the contact tip.
