Installing the welding shield (Fig. 3/4)
• Install the handle (14) on the welding shield (13) as
shown in Fig. 4.
• Install the protective glass (15) on the welding
shield (13) as shown in Fig. 4.
• Then fold the three sides of the welding shield. The
two sides each connect to the top with two press
studs.
Starting up
Connecting to the mains power supply
Before you connect the power cable (8) to the mains
power supply, make sure that the data on the rating
plate is the same as that for your mains supply.
Connect the machine to a properly installed protec-
tive contact socket, with at least 16A circuit breaker.
Danger! The mains plug may only be replaced by a
qualified electrician.
Connecting the welding cable (Fig. 5)
Danger! Always make sure the device is unplugged
before carrying out any connection work on the weld-
ing cable (9/10)! Connect the welding cable as shown
in Fig. 5. To do so, connect the two connectors on the
electrode holder (9) and the ground terminal (10) to
the corresponding quick-lock couplings (6/7) and lock
the connectors in place by turning them in a clock-
wise direction.
The cable with the electrode holder (9) is normally
connected to the positive pole (6) and the cable with
the ground terminal (10) to the negative pole (7).
Switching ON/OFF (Fig. 1)
Switch on the machine by moving the On/Off switch
(1) to the "I" position. The indicator lamp for operation
(4) then comes on. Switch off the machine by moving
the On/Off switch (1) to the "0" position. The indicator
lamp for operation (4) then goes out.
Welding preparations
Connect the earth terminal (10) 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.
Welding (Fig. 1/5)
Connect all the electrical connections for the power
supply and for the welding current circuit. Most coat-
ed electrodes are connected to the positive pole.
However, some types of electrode have to be con-
nected to the negative pole. Ensure that you observe
the information supplied by the manufacturer in rela-
tion to the type of electrode and correct polarity. Fit
the welding cables (9/10) to the quick-lock couplings
(6/7) accordingly. Then fasten the unsheathed end of
the electrode in the electrode holder (9) and connect
the ground terminal (10) 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 (2).
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 elec-
trode and current strength on a test part.
Electrode (Ø mm): Welding current (A)
1.6 40 - 50 A
2 40 - 80 A
2.5 60 - 110 A
3.2 80 - 130 A
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 diam-
eter of the electrode.
This distance should be kept as constant as possible
during the welding process. The angle of the elec-
trode in the direction in which you are working should
be 20/30°.
Always use tongs to remove spent electrodes and to
move parts that you have just welded. Please note
that the electrode holder (9) must always be put down
so that it is insulated after you have completed the
welding work.
Do not remove the slag until the weld has cooled.
If you want to continue a weld after an interruption, the
slag from your initial attempt must first be removed.
Overheating guard
The welding set is fitted with an overheating guard
that protects the welding transformer from overheat-
ing. If the overheating guard trips, the control lamp
(5) on your set will be lit. Allow the welding set to cool
for a time.
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.

Maintenance and Care

Danger!
Always pull out the mains power plug before starting
any cleaning work.
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 immedi-
ately each time you have finished using it.
