WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
• Install and ground the unit in accordance with instruction manual.
• 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.
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.

1 SAFETY

5 OPERATION
General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual. Read it through before you start using the equipment!
WARNING!
Rotating parts can cause injury, take great care.
WARNING!
To prevent the reel from sliding off
the hub: Lock the reel in place by
turning the red knob as shown on
the warning label attached next to
the hub.
WARNING!
Secure the equipment - particularly
if the ground is uneven or sloping.

5 OPERATION
0463 344 101 - 14 - © ESAB AB 2022
5.3 Wire feed pressure
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.
Figure A Figure B
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 approx. 5 mm from the piece of wood (figure A) the feed
rollers should slip.
If you hold the welding torch approx. 50 mm from the piece of wood, the wire should be fed
out and bend (figure 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 the new wire for 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 track and into the outlet
nozzle and the wire guide.
• Secure the pressure sensor.
• Close the side panel.
5.5 Overheating protection
When the power source is switched on with the mains switch [1], indicator lamp [2] is on and
lamp [3] off - the equipment is ready to operate. If the internal temperature becomes too high,
the welding is interrupted and disabled. This state is indicated by lighting of the orange
indicator lamp [3] on the front of the power source. It resets automatically when the
temperature has fallen.

6 MAINTENANCE
0463 344 101 - 15 - © ESAB AB 2022
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, if readjustment is required, follow the instructions below.
Adjust the brake hub so that wire is slightly slack when wire feed stops.
•Adjusting the braking torque:
○ Turn the red handle to the locked
position.
○ Insert a screwdriver into the
springs in the hub.
Turn the springs clockwise to reduce
the braking torque.
Turn the springs counter-clockwise to
increase the braking torque.
Note: Make sure you turn both springs
the same amount.
Welding torch
• Cleaning and replacement of the welding torch's wear parts should take place at
regular intervals in order to achieve trouble-free wire feed. Blow the wire guide clean
regularly and clean the contact tip.

7 TROUBLESHOOTING
0463 344 101 - 16 - © ESAB AB 2022
7 TROUBLESHOOTING

technican.
Type of fault Actions
No arc • Check that the mains power supply switch is turned on.
• Check that the welding current supply and return cables
are correctly connected.
• Check that correct current value is set.
Welding current is
interrupted during welding
• Check whether the thermal overload trip has operated
(indicated by the orange lamp on the front).
• Check the main power supply fuses.
Thermal overload trips
operate frequently
• Check to see whether the air inlets/outlets are clogged.
• Make sure that you are not exceeding the rated data for
the power source (i.e. that the unit is not being
overloaded).
Poor welding performance • Check that the welding current supply and return cables
are correctly connected.
• Check that the correct current value is set.
• Check that the correct welding wires are being used.
• Check the main power supply fuses.
• Check the wire feed unit - if proper rolls are applied and
properly set the pressure of the wire feeder's pressure
rollers.
