5. Fitting the carrying strap (Fig. 3/4)
Attach the carrying strap (11) as shown in Fig. 3/4.
6. Starting up
Connecting to the mains power supply
Before you connect the power cable (7) to the mains
power supply, make sure that the data on the rating
plate is the same as that for your mains supply.
Important!
The mains plug may only be replaced by
a qualified electrician.
Connecting the welding cable (Fig. 5)
Important! Always make sure the device is
unplugged before carrying out any connection work
on the welding cable (8/9)! Connect the welding
cable as shown in Fig. 5. To do so, connect the two
connectors (12) on the electrode holder (8) and the
ground terminal (9) to the corresponding quick-lock
couplings (5/6) and lock the connectors (12) in place
by turning them in a clockwise direction.
The cable with the electrode holder (8) is normally
connected to the positive pole (5) and the cable with
the ground terminal (9) to the negative pole (6).
Switching ON/OFF (Fig. 2)
To switch on the device, turn the potentiometer (1) in
a clockwise direction from the zero position on the
welding current scale (2). The indicator lamp for
operation (3) then comes on. To switch off the
device, turn the potentiometer (1) in a counter-
clockwise direction back to the zero position on the
welding current scale (2). The indicator lamp for
operation (3) then goes out.
7. Welding preparations
Connect the earth terminal (9) direct to the part to be
welded or to the support on which the part is resting.
Ensure that the earth terminal is in direct contact with
the part to be welded. You should therefore avoid
coated surfaces and/or insulated materials. The
electrode holder cable has a special clamp at one
end, which is used to secure the electrode. The
welding safety shield must be used at all times for
welding. It protects your eyes from the radiation
emitted by the arc and nevertheless enables you to
watch the welding process.
8. Welding
Connect all the electrical connections for the power
supply and for the welding current circuit. Most
coated electrodes are connected to the positive pole.
However, some types of electrode have to be
connected to the negative pole. Ensure that you
observe the information supplied by the
manufacturer in relation to the type of electrode and
correct polarity. Fit the welding cables (8/9) to the
quick-lock couplings (5/6) accordingly. Then fasten
the unsheathed end of the electrode in the electrode
holder (8) and connect the ground terminal (9) to the
part you wish to weld. Ensure that a good electric
contact is made. Switch on the device and set the
welding current, depending on the electrode used,
using the potentiometer. Hold the safety shield in
front of your face and rub the tip of the electrode on
the part you wish to weld as if you were striking a
match. This is the best method of igniting an arc.
Check that you have the correct electrode and
current strength on a test part.

Important!
Do not dab the workpiece with the electrode since it
could be damaged, making it more difficult to ignite
the arc.
As soon as the arc has ignited, attempt to keep it a
distance from the workpiece equivalent to the
diameter of the electrode.
This distance should be kept as constant as possible
during the welding process. The angle of the
electrode in the direction in which you are working
should be 20/30°.
