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

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 user’s 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

(12)

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.
