3 INTRODUCTION
MEK 20C is a portable wire feed unit with four--roller drive, designed for MIG/MAG
welding in conjunction with Esab’s A10 wire feed system. The wir e feed unit can
accommodate a 200 mm diameter wire reel.
The wire feed unit is m ounted on an insulated protective frame equipped with
runners.
The wire feed unit is controlled from the PUA1 controller, see additional information
under Operation.
Details of ESAB’s accessories for the wire feed units can be found on page
106.

4 TECHNICAL DATA
Dimensions lxwxh 500x195x300
Weight 14 kg
Wire feed speed 2-- 25 m/min
Voltage 42V 50--60Hz
Power consumption 300 VA
Torch connection EURO
5 INSTALLATION
The in stallatio n must be executed by a professional.
WARNING!
This product is intended for industrial use. In a domestic environment this product may cause radio
interference. It is the user’s responsibility to take adequate precautions.
WARNING!
When welding in an environment with increased electrical danger, only power sources intended
for this environment may be used. These power sources are marked with the symbol .
5.1 Termination resistance
The termination resistance must be connected to the ends of the CAN bus to prevent
communication problems. The controller has a built--in terminator, but the power
source and wire feed unit do not.
The terminator should be fitted as follows depending on how the units are
connected:
Controller connected to wire feed unit.
The termination resistance must be con-
nected to the rear of the power source.
(Already connected this way on deliv-
ery).
GB

Controller connected to power so u rce.
The termination resistance
must be connected to the front
of the wire feed unit.
6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 36. Read through before you start using the equipment!
WARNING!
Assure that the side panels are closed during operation.
To prevent the reel 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!
WARNING!
Rotating parts can cause injury, take great care.
WARNING!
There is a risk of tipping if the wire feed unit is fitted with a counterbalance arm. Secure the
equipment, especially if used on an uneven or sloping surface.
When moving the equipment use intended handle. NOTE! Never pull on the gun.

The wire feed speed and voltage
The wire feed speed and voltage can be adjusted using the PUA1 controller in set and
measure m odes. If you want to use the potentiometers on the front of the wire feed unit
then the toggle switch inside the wire feed unit must be in the upper position and the
PUA1 controller should be set for remote operation.
Remote control
To use a remote control, the toggle switch inside the wire feed unit must be switched
to remote, and the PUA1 controller must also be set to remote, as above. If you want
to change the wire feed and voltage parameters using the controller, you m ust switch
from “remote“ to measure mode or set mode.

bm22d12e
6.2 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 insolated 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 m m from the piece of wood, the wire should be
fed out and bend (fig. 2).
6.3 Changing / loading wire
S Open the side panel.
S Disconnect the pressure sensor by folding it backwards, the pressure rollers
slide up.
S Straighten out the new wire 10--20 cm. F ile away burrs and sharp edges from the
end of the wire before inserting it into the wire feed unit.
S Make sure that the wire goes properly into the feed roller’s track and into the
outlet nozzle or wire guide.
S Secure the pressure sensor.
S Close the side panel.
6.4 Changing feed rollers on
S Open the side panel.
S Disconnect the pressure sensor (1) by folding it
backwards.
S Disconnect the pressure rollers (2) by turning the
axle (3) 1/4 turn clockwise and pulling out the axle.
The pressure rollers disconnect.
S Disconnect the feed rollers (4) by unscrewing the nuts
(5) and pulling out the rollers.
During installation, repeat the above in the reverse order.
Choice of tracks in the feed rollers
Turn the feed roller with the dimensioning mark for the required
track towards you.

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
Wire feed unit
Check regularly that the wire feed unit is not clogged with dirt.
S Cleaning and replacement of the wire feed unit mechanism’s worn parts should
take place at r egular intervals in order to achieve trouble--free wire feed. Note
that if pre--tensioning is set too hard, this can r esult 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.
S Adjusting the braking torque:
S Turn the red handle to the locked position.
S Insert 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.
Weldin g gun
S Cleaning 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.
