3 INTRODUCTION

The Feed L302 with control panel M08 and Feed L304 with control panel M09 wire

feed units are intended for MIG/MAG welding with the Mig L405 power source.

They come in different variants, see page 16.

The feed units can be used together with wire on ESAB's MarathonPact, or on wire

bobbin Ø 300 mm.

They can be installed either at the power source, suspended above the workplace,

on a support arm or on the floor with or without wheel set.

ESAB's accessories for the product can be found on page 21.

3.1 Equipment

The wire feed units are supplied with an instruction manual and stickers.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Apparatus marked IP2X are intended for indoor use.

Enclosure class

The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid

objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

Duty cycle

The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at

a certain load without overloading. The duty cycle is valid for 40°C.

5 INSTALLATION

The installation must be executed by a professional.

CAUTION

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

WARNING

To prevent the reel from 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

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.

NOTE: When moving the equipment use intended handle. Never pull on the gun.

6.1 Connections and control devices

When connecting the control cable, it is

important to secure the cable with the

load-removing grommet.

Ensure that the cover is properly screwed

into place.

6.2 Explanation of function

Wire feed speed

This sets the required feed speed of the filler wire in m/minute.

2stroke

With 2-stroke, the gas flow starts followed by the wire feed when the trigger switch is

pressed in. The welding process is concluded when the trigger switch is released,

the wire feed stops and the gas stops flowing.

4stroke

With 4 stroke, the gas flow starts when the trigger switch is pressed in and the wire

feed starts when it is released. The welding process continues until the switch is

pressed in again, the wire feed stops and when the switch is released the gas stops

flowing.

Spot welding

Spot welding is used when you want to weld on short, repeated occasions with a

pre-set time.

When the trigger switch is pressed in, the gas flow starts for a period of time

governed by the printed circuit board. After this the welding process starts for the set

time. When the welding process is complete, the gas flow stops.

Cold wire feed

Cold wire feed is used to feed wire without welding voltage and gas flow.

Activation of cold wire feed: press in the trigger switch and the wire feed starts.

Gas purging

Gas purging is used to measure that gas flow or to flush the gas hoses to clean them

of any air and moisture before commencing welding. Gas purging is carried out with

the voltage and wire feed switched off.

Activation of gas purging: press in the trigger switch and gas purging starts.

Burnback time

Burnback time is a delay between the time when the wire brakes until the time when

the power source switches off the welding voltage. Too short burnback time results

in a long wire stickout after completion of welding, with a risk of the wire being

caught in the weld pool. Too long a burnback time results in a shorter stickout, with

increased risk of the arc striking back to the contact tip.

Creep start

Creep start means that the wire is fed at 50% lower speed until it comes into

electrical contact with the workpiece, at which point the speed increases to the set

speed.
