Mig C340 PRO 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 29.

6 OPERA ION
General safety regulations for the handling of the equipment can be found on
page 4. Read through before you start using the equipment!
WARNING!
Rotating parts can cause injury, take great care.
WARNING!
o 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 -- IPPING RISK!
There is a risk of tipping while transportation and operation, if the welding machine leans
more than 0

6.3 Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder pressure roller(s). It is important that the
pressure is not too great.
ig 1 ig 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. ) the feed
roller(s) 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).
6.4 Replacing and inserting wire
SOpen the side panel.
SDisconnect the pressure sensor by folding it backwards, the pressure rollers
slide up.
SStraighten out the new wire 0--20 cm. File away 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.
6.5 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.6 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.

7 MAIN ENANCE
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 29.
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.
he 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 counterclockwise to increase the braking torque. NB: Turn
both springs through the same amount.

Try these recommended checks and inspections before sending for an authorised service technican.
ype 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
