WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be d angerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from your breathing zone and
the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
S Protect your ears. Use ear defenders or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
WARNING
This product is intended for industrial use. In a domestic environment this product
may cause radio interfer ence. It is the users responsibility to take adequate pre-
cautions.
WARNING!
Rotating parts can cause injury, take
great care.
IMPORTANT!
To prevent the reel sliding off the hub: Lock the reel in place
by turning the red knob as shown on the warning label atta-
ched next to the hub.

INTRODUCTION
The A10 -- MEH 20 is a wire feed unit for MIG/MAG welding using ESAB:s A10 wire
advance system. T he MEH 20 will accept wire reels u p to 20 cm in diameter.
Hence the designation 20. The motor is controlled electronically and carries the des -
ignation E. The letter M stands for wire feed unit and H indicates the generation.
The MEH 20 has switches for 2/4 step trigger action and for normal/inch start. These
controls are located on the dividing panel behind the lid.
The socket for connection of a remote control device is on the front panel.
TECHNICAL DESCRIPTION
Casing
The wire feed unit has an aluminium casing which is divided vertically into two sec-
tion. The first section, covered by a screwed lid, contains the circuit card, potentio-
meter and solenoid valve.
The second section is covered at the side by a led. The lid is hinged at the bottom
and has a quick--action catch for fast opening. This section contains the wire feed
mechanism, drive assembly and connection terminals for the welding hose.
Mounted on the dividing panel behind the feed mechanism are switches for 2/4 step
trigger action and for normal/inch start.
The potentiometer for setting the burn--back time can be reached through a hole in
the dividing panel. In the rear panel is a grommet through which the welding cable
passes from the power source.
Wire feed mechan ism
The wire feed mechanism is driven by a permanent magnet electric motor.
The motor is united to a worm gearbox with a feed roller on the output shaft. The
gears on the feed shaft drive a thrust roller. T he wire is advanced by the rollers and
power is received from two driving rollers.
Pressure is applied to the wire by a blade spring attached to the bracket supporting
the thrust roller. The blade spring is lever--shaped and allows the thrust roller to be
moved out of the way when changing the wire or cleaning the outlet nozzle. When
the thrust roller is released the same pressure is applied to the wire as before. This
pressure can be adjusted using the knob.
The connection plate on the wire feed unit is used for connecting welding current,
control current, shielding gas, and the wire, all in a single coupling. The wire outlet
nozzle is attached to the connection plate by a locking pin. No tools a re needed to
replace the nozzle. On the connection plate is a power relay which closes when cur-
rent flows in the welding circuit.
The feed roller and thrust roller have three grooves for different wire dimensions.
The rollers need not be changed when changing to thicker or thinner wire, just
moved sideways. The position of the feed roller on the shaft is adjusted using one or
two shims. The thrust roller automatically adjusts to the correct position in relation to
the feed roller.
The feed mechanism is insulated from the casing.
Regulator equipment
The electronic components are on a circuit card mounted on the dividing panel. In-
ternal cables are connected to the card by multipin connectors. The control cable is
connected to a bolted terminal.

MAINTENANCE
Regularly maintenance is important for reliable and safe operations.
S Cleaning and replacement of the wire feed mechanism’s wear parts should take
place periodically to ensure trouble free wire feed.
S Note that an excessive pressure setting can result in abnormal wear on the pres-
sure roller, feed roller and wire liner.
Ordering spare parts
When ordering parts please state the machine model, serial number and name and
spare part number as shown in the list of spare parts.
