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.
Danger! The mains plug may only be replaced by
a qualifi ed electrician.
Connecting the welding cable (Fig. 5)
Danger! Always make sure the device is un-
plugged 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 connec-
tors (12) in place by turning them in a clockwise
direction.
The cable with the electrode holder (8) is nor-
mally 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 pow-
er 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 ma-
nufacturer 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 ter-
minal (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.
Electrode (Ø mm): .................Welding current (A)
1,6............................................................40-50 A

2,5 ....................................................... 60 - 110 A
Important!
Do not dab the workpiece with the electrode since
it could be damaged, making it more diffi cult 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 pos-
sible during the welding process. The angle of the
