3 INTRODUCTION
ESABMig C280 & ESABMig C340 are step controlled power sources in a compact
design, intended for welding with solid steel, stainless steel or aluminium wire as well
as tubular wire with or without shielding gas.
The possibility of welding with homogeneous wire/shielding gas and welding with
gasless tubular wire is obtained by switching the + and −connections on the
switching terminal above the wire feed unit.
ESAB’s accessories for the product can be found on page 176.

6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 48. Read through before you start using the equipment!
WARNING!
Rotating parts can cause injury, take great care.
WARNING −TIPPING RISK!
There is a risk of tipping while transportation and operation, if the welding machine leans
more than 10o. In that case appropriate securing has to be provided !

6.2 Function explanation
6.2.1 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.2.2 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1 Inspection and cleaning
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. 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. Ordering number can be found on page 176.
Welding gun
SCleaning and replacement of the welding gun’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.
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 anticlockwise to increase the braking torque. NB: Turn both
springs through the same amount.

8 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
9 ORDERING OF SPARE PARTS
ESABMig C280 & ESABMig C340 is designed and tested in accordance with the inter-
national and European standards IEC/EN 60974−1 and EN 50199. It is the obligation of
