must be on the outside. (Fig. 9).
Bend the top of the welding screen frame (s)
inwards (Fig. 10/1) and fold down the top corners
(Fig. 10/2) Now bend the outer sides of the
welding screen frame (l) inwards (Fig. 10/3) and
connect them by pressing the top corners and
outer sides together. When the retaining pins
engage, you should be able to hear 2 clear clicks
on each side (Fig. 10/4).
When the top corners of the welding screen are
connected as shown in Figure 11, place the
screws for the handle (p) from the outside
through the three holes in the welding screen.
(Fig. 12).
Turn over the welding screen and place the
handle (r) over the threads on the three screws
for the handle (p). Secure the handle (r) to the
welding screen using the three nuts for the
handle (o). (Fig. 13).
5.2 Mains connection
Before you connect the equipment to the mains
supply make sure that the data on the rating
plate are identical to the mains data.
The equipment may only be operated from
properly earthed and fused shock-proof sockets.
5.3 Fitting the wire spool (Fig. 1, 2, 3, 14 – 22)
The wire spool is not supplied.
5.3.1 Wire types
Various welding wires are required for different
applications. The welding set can be used with
welding wires with a diameter of 0.9 mm. The
appropriate feed rollers and contact tubes are
supplied with the set. The feed roller, contact tube
and wire cross-section must always match each
other.
5.3.2 Wire spool capacity
Wire spools with a maximum weight of 0.4 kg can be
fitted in the welding set.
5.3.3 Inserting the wire spool
Unlock the housing cover (Fig. 1/3) by turning
the fastening screw (Fig. 6/12) through 90° and
flip open the cover.
Check that the windings on the spool do not
overlap so as to ensure that the wire can be
unwound evenly.

Inserting the wire spool (Fig. 14, 15)
Place the wire spool (A) on the spool holder (B).
Ensure that the end of the welding wire is unwound
on the side of the wire guide, see arrow.
Inserting the welding wire and adjusting the wire
guide (Fig. 16-22)
Push the pressure roller spring (K) upwards and
swing it forwards (Fig. 16).
Pull the pressure roller holder (J) with the
pressure roller (I) and pressure roller spring (K)
downwards (Fig. 17).
Undo the screws for the feed roller holder (E)
and pull off the feed roller holder (F) upwards
(Fig. 18).
Check the feed roller (G). The appropriate wire
thickness must be specified on the top of the
feed roller (G). The feed roller (G) is fitted with
two guide grooves. Turn the feed roller (G) over
if necessary or replace it. (Fig. 19).
Position the feed roller holder (F) again and
secure it.
Remove the gas nozzle (Fig. 2/10) from the
burner (Fig. 2/11) by turning it clockwise,
unscrew the contact tube (Fig. 3/15). (Fig. 2 – 3).
Place the hose package (Fig. 1/9) on the floor as
straight as possible pointing away from the
welding set.
Cut off the first 10 cm of the welding wire to
produce a straight cut with no shoulders, warping
or dirt. Deburr the end of the welding wire.
Push the welding wire through the guide tube (C)
between the pressure and feed rollers (G/I) into
the hose package mounting (H). (Fig. 20)
Carefully push the welding wire by hand into the
hose package until it projects out of the hose
package by approx. 1 cm at the burner (Fig.
2/11).
Undo the adjusting screw for counter-pressure
(L) a few turns. (Fig. 22).
Push the pressure roller holder (J) with pressure
roller (I) and pressure roller spring (K) upwards
again and attach the pressure roller spring (K) to
the adjusting screw for counter-pressure (L)
again (Fig. 21).
Now set the adjusting screw for counter-pressure
(L) so that the welding wire is positioned firmly
