To set the gas fl ow rate, fi rst release the clamp
lever (Fig. 26/K) on the wire feed unit to prevent
unnecessary wire wear (Fig. 5.4.3). Connecting to
the mains (see point 5.3), set the ON/OFF/Wel-
ding current switch (Fig. 1/7;8) to setting 1; 230
V/400 V and press the burner switch (Fig. 5/25) to
start the gas fl ow. Now set the required gas deli-
very rate on the pressure reducer (Fig. 4/19).
Turn the rotary knob (Fig. 4/24) counter-clockwi-
se:
Lower gas delivery rate
Turn the rotary knob (Fig. 4/24) clockwise:
Higher gas delivery rate
Secure the pressure roller spring (Fig. 26/K) to the
wire feed unit again.
6.2 Electrical connection
6.2.1 Mains connection
See point 5.3
6.2.2 Connecting the earth terminal (Fig.
1/10)
Connect the welding set’s earth terminal (10) 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 and the shielding gas has also been con-
nected, 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, wire feed and gas fl ow
rate (see 6.1.1 – 6.1.3) as required.
Hold the welding screen (Fig. 3/17) in front of your
face and move the gas nozzle to the point on the
workpiece where you wish to complete the weld.
Now press the burner switch (Fig. 5/25).
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, wire
feed speed and gas delivery rate 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 allo-
wed to fall through the workpiece.
6.4 Safety equipment
6.4.1 Thermostat
The welding set is fi tted with an overheating
guard that protects the welding transformer from
overheating. If the overheating guard trips, the
control lamp (3) on your set will be lit. Allow the
welding set to cool for a time.
7. Replacing the power cable
Danger!
If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
8. Cleaning, maintenance and
ordering of spare parts
Danger!
Always pull out the mains power plug before star-
ting any cleaning work.
8.1 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 with compressed air at low
pressure.
•
We recommend that you clean the device
immediately each time you have finished
using it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could at-
tack the plastic parts of the equipment. Ensu-
re that no water can seep into the device. The
ingress of water into an electric tool increases
the risk of an electric shock.
8.2 Maintenance
There are no parts inside the equipment which
require additional maintenance.
