between the pressure roller (I) and feed roller (G)
without being crushed. (Fig. 22).
Screw the appropriate contact tube (Fig. 3/15) for
the welding wire diameter on to the burner (Fig.
2/11) and fit the gas nozzle(Fig. 2/10), turning it
clockwise.
Set the adjusting screw for the roller brake (D) so
that the wire can still be moved and the roller
stops automatically after the wire guide has been
braked.
6. Operation
6.1 Setting
Since the welding set must be set to suit the specific
application, we recommend that the settings be
made on the basis of a test weld.
6.1.1 Setting the welding current
The welding current can be set to 2 different levels
using the welding current adjustment switch (Fig.
1/6). The required welding current depends on the
material thickness, the required penetration depth
and the welding wire diameter.
6.1.2 Setting the wire feed speed
The wire feed speed is automatically adjusted to the
current setting. The final wire feed speed setting can
be made on the welding wire speed controller (Fig.
1/5). It is advisable to start with the medium setting
and to re-adjust the speed as necessary. The
required quantity of wire depends on the material
thickness, the penetration depth, the welding wire
diameter and also the size of the gap to be bridged
between the workpieces you wish to weld.
6.2 Electrical connection
6.2.1 Mains connection
See point 5.2
6.2.2 Connecting the earth terminal (Fig. 1/8)
Connect the welding set's earth terminal (8) in the
immediate vicinity of the welding position if possible.
Ensure that the contact point is bare metal.
6.3 Welding
When all the electrical connections for the power
supply and welding current circuit have been made,
you can proceed as follows:
The workpieces for welding must be clear of paint,
metallic coatings, dirt, rust, grease and moisture in
the area where they are to be welded.

Set the welding current and wire feed (see 6.1.1 –
6.1.3) as required.
Hold the welding screen (Fig. 4/13) in front of your
face and move the welding nozzle to the point on the
workpiece where you wish to complete the weld.
Now press the burner switch (Fig. 2/14).
When the arc is burning, the welding set will feed
wire into the weld pool. When the weld nugget is
large enough, move the burner slowly along the
required edge. Move it to and fro if necessary to
enlarge the weld pool a little.
Find the ideal setting of the welding current and wire
feed speed by carrying out a test weld. Ideally an
even welding noise will be audible. The penetration
depth should be as deep as possible, but the weld
pool must not be allowed to fall through the
workpiece.
Do not remove the slag until the weld has cooled. If
you want to continue a welding job on an interrupted
weld seam, the slag from your initial attempt must
first be removed.
6.4 Safety equipment
6.4.1 Thermostat
The welding set is fitted with an overheating guard
that protects the welding transformer from
overheating. If the overheating guard trips, the
control lamp (2) on your set will be lit. Allow the
welding set to cool for a time.
7. Cleaning, maintenance and ordering
of spare parts
Always pull out the mains power plug before starting
any cleaning work.
7.1 Cleaning
Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
down with compressed air at low pressure.
We recommend that you clean the equipment
immediately after you use it.
Clean the equipment regularly with a damp cloth
and some soft soap. Do not use cleaning agents
or solvents; these may be aggressive to the
plastic parts in the equipment. Ensure that no
water can get into the interior of the equipment.
