1 SAFETY
Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who works on or
near the equipment observes all the relevant safety precautions. Safety precautions must meet the
requirements that apply to this type of equipment. The following recommendations should be ob
served in addition to the standard regulations that apply to the workplace.
All work must be carried out by trained personnel well-acquainted with the operation of the equip
ment. Incorrect operation of the equipment may lead to hazardous situations which can result in in
jury to the operator and damage to the equipment.

5.2 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
5.3 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.

5.4 Polarity change
The power source is delivered with the welding wire connected to the plus pole.
Some wires, e.g self shielded cored wires, are recommended for welding with
negative polarity. Negative polarity means that the wire is connected to the minus
pole and the return cable to the plus pole.
Check the recommended polarity for the welding wire you want to use.
5.5 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 great.
Fig 1 Fig 2
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 gun approx. 5 mm from the piece of wood (fig. 1) the feed
rollers should slip.
If you hold the gun approx. 50 mm from the piece of wood, the wire should be
fed out and bend (fig. 2).

5.6 Replacing and inserting wire
SOpen the side panel.
SDisconnect the pressure sensor by folding it backwards, the pressure rollers
slide up.
SStraighten out 10-20 cm of new wire. File off any burrs and sharp edges from the
end of the wire before inserting it into the wire feed unit.
SMake sure that the wire goes properly into the feed roller track and into the outlet
nozzle and the wire guide.
SSecure the pressure sensor.
SClose the side panel.
6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
6.1 Inspection and cleaning
Power source
Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced
pressure. This should be done more frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating. To avoid
this you can use an airfilter.
The airfilter is an accessory. Order number can be found on page 29.
Welding gun
SThe welding gun'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.
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.
SAdjusting the braking torque:
STurn the red handle to the locked position.
SInsert 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. NB: Turn
both springs the same amount.

7 FAULT TRACING
Try these recommended checks and inspections before sending for an authorised
service technican.
Type of fault Actions
No arc SCheck that the mains power supply switch is turned on.
SCheck that the welding current supply and return cables are
correctly connected.
SCheck that correct current value is set.
Welding current is interrupted
during welding
SCheck whether the thermal overload trip has operated
(indicated by the orange lamp on the front).
SCheck the main power supply fuses.
Thermal overload trips
operate frequently
SCheck to see whether the air filters are clogged.
SMake 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 SCheck that the welding current supply and return cables are
correctly connected.
SCheck that the correct current value is set.
SCheck that the correct welding wires are being used.
SCheck the main power supply fuses.
SCheck the wire feed unit - if proper rolls are applied and
properly set the pressure of the wire feeder's pressure rollers
8 ORDERING OF SPARE PARTS
Repair and electrical work should be performed by an authorised ESAB service
technician. Use only ESAB original spare and wear parts.
Mig C280 PRO, Mig C340 PRO is designed and tested in accordance with the interna
tional and European standards 60974-1, 60974-5 and 60974-10 . It is the obligation of
