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
0460 742 001 -6- © ESAB AB 2017
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 that there are no inflammable
materials nearby.
• Do not use on closed containers.

5 OPERATION
0460 742 001 - 12 - © ESAB AB 2017
5 OPERATION
General safety regulations for handling the equipment can be found in chapter "SAFETY".
Read through before you start using the equipment!

5 OPERATION
0460 742 001 - 13 - © ESAB AB 2017
5.1 Connections and control devices
1. Control panel, see separate instruction
manual
5. Connection (-) TIG: Welding torch MMA:
Welding cable or return cable
2. Connection for remote control unit 6. Connection (+) TIG: Return cable MMA:
Return cable or welding cable
3. Connection for start signal from the
welding torch
7. Mains voltage switch
4. Connection for gas to the torch 8. Connection for shielding gas
5.2 Connection of welding and return cable
The power source has two outputs, a positive terminal (+) and a negative terminal (-), for
connecting welding and return cables. The output to which the welding cable is connected
depends on the welding method or type of electrode used.
Connect the return cable to the other output on the power source. Secure the return cable's
contact clamp to the work piece and ensure that there is good contact between the work
piece and the output for the return cable on the power source.
For MMA welding, the welding cable can be connected to the positive terminal (+) or
negative terminal (-) depending on the type of electrode used. The connecting polarity is
stated on the electrode packaging.
5.3 Fan control
The power source has a time control that means that the fans continue to run for 6.5 minutes
after welding has stopped, and the unit switches to energy-saving mode. The fans start again
when welding restarts.
The fans run at reduced speed for welding currents up to 110 A, and at full speed for higher
currents.

5 OPERATION
0460 742 001 - 14 - © ESAB AB 2017
5.4 Overheating Protection
The welding power source has overheating protection that operates if the temperature
becomes too high. When this occurs the welding current is interrupted and a fault code is
displayed on the control panel.
The overheating protection resets automatically when the temperature has fallen.
5.5 TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten electrode,
which does not itself melt. The weld pool and the electrode are protected by shielding gas.
For TIG welding, the welding power source is supplemented with:
• TIG torch, see chapter "ACCESSORIES"
• an argon gas cylinder
• an argon gas regulator
• tungsten electrode
5.6 MMA welding
For MMA welding, the power source is supplemented with:
• welding cable with electrode clamp, see chapter "ACCESSORIES"

6 MAINTENANCE
0460 742 001 - 15 - © ESAB AB 2017
6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorised personnel) may
remove the safety plates to connect or carry out service, maintenance or repair work on
welding equipment.
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 Power unit
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on: the welding process, arc times,
placement, and the surrounding environment. It is normally sufficient to blow the power
source clean with dry compressed air (reduced pressure) once a year. Clogged or blocked
air inlets and outlets otherwise result in overheating.
6.2 Welding torch
Wear parts should be cleaned and replaced at regular intervals in order to achieve
trouble-free welding.

7 FAULT TRACING
0460 742 001 - 16 - © ESAB AB 2017
7 FAULT TRACING
Try these recommended checks and inspections before sending for an authorized service
technician.
Type of fault Action
No arc. • Check that the mains power supply
switch is turned on.
• Check that the welding and return cables
are correctly connected.
• Check that the correct current value is
set.
• Check the mains power supply fuses.
Welding current is interrupted during welding. • Check whether the overloading protection
has deployed (indicated in the control
panel).
• Check the main power supply fuses.
The overheating protection trips frequently. • Make sure that you are not exceeding the
rated data for the welding power source
(i.e. that the unit is not being overloaded).
• Check that the air inlets and outlets are
not obstructed or blocked.
Poor welding performance. • Check that the welding and return cables
are correctly connected.
• Check that the correct current value is
set.
• Check that the correct electrodes are
being used.
• Check the main power supply fuses.
• Check gas flow and gas quality.
