2 INTRODUCTION
2.1 General
The MEI 21 is a wire feed unit for mechanized TIG welding.
It is designed for use with the LTS 160/250/320 or LTP 450 welding power source
and the PRB or PRC welding tool.
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.
Two p ressure 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 LTS 160/250/320 or LTP 450 welding power source.

3 INSTALLATION
3.1 General
The installation must be execu ted by a professional.
WARNING
Rotating parts can cause injury, take great care.
Connect the wire feed unit cable to the welding power source.
3.2 Connecting the wire conduit
S Unscrew the bolt on the output side of the wire feed unit.
S Connect the wire conduit and tighten the bolt.
S Check that the wire conduit is in the right position between the feed rollers and
that it bottoms.
3.3 Replacement/Insertion of filler wire
S Release the feed roller pressure spring.
S Remove the cover of the bobbin.
S Rewind any existing wire out of the wire feed unit and remove the wire r eel.
S Straighten out the new filler wire 10--20 cm. File off any sharp edges of the filler
wire before inserting it into the wire feed unit. Make sure the wire comes right in
the grooves of the feed rollers and the outlet nozzle/wire conduit.
S Retension the spring.
S Press the reel cover in place.
S Advance the filler wire till it sticks out some ten centimetres through the quick--
coupling.
S Insert the filler wire m anually into the tool part of the quick--coupling. Interlock the
two parts of the coupling.
S Loosen the joint nipple from the hose support on the tool and place the tool so
that the wire conduit is straight.
S Start the wire feed again and feed the filler wire out through the nozzle.
S Trim the end of the filler wire.
S Fit the joint nipple on the hose support.
