3 INTRODUCTION

The MEI 21 is a wire feed unit for mechanized TIG welding.

The unit consists of the following components:

1. Tube frame

2. Feed unit

3. Drive motor

4. Reel holder

5. Cable

6. Wire conduit

The MEI 21 is designed for wire diameters Ø 0.6 to Ø 0.8 mm.

The reel holder (4) will accept reels with an outer diameter of 200 mm and a width of

60 mm. The cover, which is removed to check or change the wire, is held by snap

fasteners.

A DC motor (3) with gear wheel drives the two feed rollers through a cog.

The DC motor is provided with a pulse transducer with feedback coupling to the

welding power source.

The feed rollers have two tracks for wire and each track is designed for a determined

wire dimension.

Two pressure rollers, which provide the necessary friction between the wire and the

feed roller, are mounted in a spring mechanism that allows the pressure to be

adjusted.

Motor cable ( 5) is provided for connecting the MEI 21 to the welding power source.

MEI 21 is controlled over the welding power source.
