Danger!
The electric power tool generates an electro-
magnetic fi eld during operation. Under certain
circumstances this fi eld may actively or passively
impede medical implants. To reduce the risk of
serious or fatal injuries, we recommend persons
with medical implants to consult their doctor and
the manufacturer of the medical implant prior to
using the equipment.

5. Before starting the equipment

Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
Warning!
Always pull the power plug before making
adjustments to the equipment.
Connecting the welding cable (Fig. 4)
Danger! Always make sure the machine is un-
plugged before carrying out any connection work
on the welding cable (8/9)!
Connect the welding cable as shown in Fig. 4. To
do so, connect the two connectors on the elec-
trode holder (8) and the ground terminal (9) to
the corresponding quick-lock couplings (5/6) and
lock the connectors 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) for welding with coated rod electrodes.
Switching ON/OFF (Fig. 2/3)
Switch on the machine by moving the On/Off
switch (11) to the "ON" position. The indicator
lamp for operation (3) then comes on. Switch off
the machine by moving the On/Off switch (11) to
the "OFF" position. The indicator lamp for operati-
on (3) then goes out.
Caution! Before you switch on the machine,
make sure that the selector switch for electrode/
TIG welding (12) is set to electrode welding.
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 insulation materials.

GB
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 while still enabling
you to watch the welding process (not included).

6. Operation

Welding
After you have made all the electrical connections
for the power supply and for the welding circuit,
you can proceed as follows:
Most coated electrodes are connected to the
positive pole. However, some types of electrode
have to be connected to the negative pole. Ensu-
re that you observe the information supplied by
the manufacturer in relation to the type of electro-
de and correct polarity.
Insert the unsheathed end of the electrode into
the electrode holder (8) and connect the earth ter-
minal (9) to the part you wish to weld. Ensure that
a good electric contact is made.
Switch on the machine at the On/Off switch (11)
and use the potentiometer for setting the wel-
ding current (1) to set the welding current which
matches the electrode you want to use. 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 the arc.
Check on a test part that you have the correct
electrode and current strength.

Caution!
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, try to keep it at
a distance from the workpiece which is equal to
the diameter of the electrode being used. This
distance should be kept as constant as possible
