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 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!

2 INTRODUCTION
MED 304 is a wire feed unit for MIG/MAG welding.
It is a component of the A--10 system.
MED 304 has an electronically controlled electric pusher motor that advances the
wire through the welding hose to the gun.
2.1 TECHNICAL DESCRIPTION
bm08d00
1
MED 304 has two motors (1) and two pairs of rollers, each comprising a feed roller
(5) and pressure roller (4). T he rollers have toothed rings. The motors drive the feed
rollers, which in turn drive the pressure rollers.
The motors are connected in series and each contributes the same driving force.
Any slip due to differences in the diameters o f the rollers will therefore not affect the
uniform feed.
The pressure rollers are incorporated in a bogie that is supported so that the pres-
sure exerted by both pairs of rollers is the same.
The bogie is mounted on a lever, which is fitted with a spring --loaded arm (3). This
unit can be easily removed, for example when changing the wire size.
The pressure exerted on the wire by the rollers is controlled by a knob (2), that acts
on the spring--loaded arm. There is no need to adjust this knob to remove the pres-
sure roller. T his means that the pressure is unchanged when the pressure roller is
replaced.
The wire runs in grooves in the r ollers, and each wire size has its own groove profile.
The lateral position of the feed roller is adjusted using spacers so that the correct
groove is aligned with the wire.
The pressure roller automatically positions itself correctly.
MED 304 is equipped with inch start, which ensures smoother arc ignition when
welding with large diameter wire. The units also provide 2 stroke or 4 stroke arc con -
trol.
To simplify the replacement of large diameter wire the MED 304 has reversible mo-
tors. These allow the wire to be r eversed out of the welding hose.
The wire feed unit is divided into two sections. One section contains the electrical
equipment, protected by a panel. The other section is protected by a lockable panel
and contains the wire feed unit and connection socket for the welding hose. Above
the connection socket are switches for selecting 2 stroke or 4 stroke arc control and
for inch start.
Control equipment.
The electronic components are mounted on a circuit card, which is held in place by
two reatiners and screws. The wiring is connected by spade connectors and multi--
pin connectors.

3 I NSTALLATION
WARNING
This product is intended for industrial use. In a domestic environment this
product may cause radio interference. It is the users r esponsibility to take
adequate precautions.
1. Connect the control cable to the power source. The cable has a 23 pin male
plug.
2. The operating voltage is 42 V, 50--60 Hz.
3. Connect the gas hose. The coupling diameter is 6 mm.
4. A 12 pin socket on the front permits the connection of a r emote control.
5. Connect the welding gun. T he welding current, control current, shielding gas and
wire are all connected through the connection socket.
6. Check that the feed rollers and nozzles are fitted as shown in the table.
WARNING!
Rotating parts can cause injury, take great care.
MED 304 can be installed in a variety of ways to suit requirement s:
Power source
Swivel unit is attached to casing of wire feed unit. This is equipped with an insulated
stud that fits the hole in the top of the welding rectifier.
Fit the insulated bushing onto the guide journal on top of the power source. Locate
the wire feed unit on the guide journal. This allows the wire feed unit to be swung
round and allows the welder freedom of movement while working.
Setofwheels
A set of wheels allows the wire feed unit to be set up independently of the power
source. This allows a greater range of movement and increases the working radius.
Support device
The wire feed unit can be suspended from the handle to give a larger working radius.
Gas--wire kit
An accessory that permits wire feed without power on (inching) and gas purging
without wire feed.

4OPERATION
Check that the wire feed unit is fitted with the correct nozzles and feed rollers for the
selected size and type of wire, refer to the table under Installation.
Connect the return cable to the work piece.
The wire feed unit consists of the following main components:
S Potentiometer (1)
For setting chosen wire feed speed. Range 0--18 m/min.
S Space fo r meters (2)
S Space for optional equipment (3)
S Gun co n nection (4)
S Coupling for water cooling (5)
S Socket (6)
For connecting remote control unit.
S Switch (7)
For selecting remote control.
S Potentiometer (8)
Used to adjust welding voltage with thyristor--controlled or inverter power sour-
ces.
S Switch (9)
For selecting initial wire feed speed. T here are two settings: inch start or normal
start. With inch start the wire is fed out at low speed until the arc ignites and the
welding current flows. The speed is then increased automatically to the preset
value.
S Switch (10)
Controls function of gun switch.
2 stroke:Wire feed starts when you press the trigger and stops when you r elea-
se it.
4 stroke:Press the trigger to start welding, then release it. Welding continues
until you press the trigger again.
S Switch (11)
Reverses wire feed.
S Space for g as--wire kit

5 MAINTENANCE
Regular maintenance is important for smooth and reliable operation.
S Clean the wir e conduit regularly using compressed air and clean the gas nozzle.
S Clean and replace the wear components of the wire feed mechanism regularly to
ensure problem--free wire feed.
Note that excessive pressure on the wir e can lead to rapid wear of the pressure
rollers, feed rollers and wire conduit.
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.
6 ACCESSORIES
The following remote control devices can be connected to the wire feed unit:
S PHB 1
With planetary gear for precision control of wire feed speed.
S PHB 2
A rugged unit with two potentiometers for coarse and fine adjustment of wire
feed speed.
S PAB 6
Programmer. PAB 6 is designed for the remote control of voltage and current. To
permit r emote control of voltage the power source must be a thyristor or inverter
model. T he programmer is connected to the remote socket on MED 304.
3 different sets of welding parameters can be programmed using PAB 6. A
switch on the unit allows you to switch between programs. By fitting an extra
switch to the welding gun you can switch between 2 of the 3 preset welding
programmes using the gun.
S PAE4
Programmer. PAE 4 allows 5 sets of welding parameters ( current/voltage) to be
pre--programmed. A switch on the front allows you to switch between programs.
There is also a knob for adjusting the arc length.
