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 S HOULD 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 dangerous 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!

3 INTRODUCTION
A10-- MEH 25 is an intermediate wire feed unit for MIG/MAG--welding where the
electrode is fed forward according to ESAB:’s A10--system
By connecting an extension cable between the intermediate wire feed unit and the
wire feed unit on the power source the working radius can be increased by up to 25
m.
On MEH 25 the wire feed speed and the voltage can be controlled using potentio-
meters or a remote control unit can be connected.
The drive motor is of a permanent--magnetic design and is integrated with a worm
gear. The motor is fed with 24 V DC voltage.
MEH 25 is equipped with a heavy--duty crash bar and runners to facilitate transport.
The extensive range combined with the performance of the power source provides
you with a flexible total solution.
3.1 TECHNICAL DATA

4 INSTALLATION
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.
Connecting the extension cab le and t h e welding gun
S The extension cable is connected to connector (6). Make sure you insert the ex-
tension cable’s inlet nozzle before you tighten the screw (8). Connect the
14--pole sleeve plug on the extension cable’s control cable to the pin socket (7)
and tighten the nut.
S Connect the other end of the extension cable to the corresponding socket on the
power source’s wire feed unit.
S The welding gun is connected to connector (5).

Feed roller
S Make sure the right feed roller and groove is used for the selected wire size.
Each feed roller has grooves for two wire sizes. The feed roller should have the
correct marking for respective wires facing outwards, towards you.
The feed roller can be turned or replaced using another suitable roller (see the
spare parts list), by removing the screw that holds the feed rollers.
WARNING!
Rotating parts can cause injury, take great care.
Feeding the wire forward
S Connect the power source to the mains supply.
S Set the wire feed speed between 1--18m/min using the potentiometer (2) on the
intermediate wire feed unit.
S Straighten out the extension cable and the welding gun cable.
S Swing out the control levers on the feed mechanism so that the feed rollers are
released. Feed the wire forward to the intermediate wire feed unit by holding the
welding gun trigger pressed in.
S Guide the wire through the nozzles over the pressure rollers and into the welding
gun’s wire--liner, swing back the pressure levers to their original positions.
S Hold the welding gun trigger pressed in until the wire is fed out through the con-
tact tip on the gun.
S By setting the correct spring tension on the rollers a slip--free wire feed is ob-
tained. If the rollers slip or in any other way do not function correctly perhaps the
pre--tension needs to be adjusted. This is carried out using the adjuster screws
on respective pressure arms. The pre--tension can be checked by using the
graduated scale on respective adjuster screws.
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.
