The welding safety shield must be used at all times for
welding. It protects your eyes from the radiation emit-
ted by the arc and nevertheless enables you to watch
the welding process.
9. Initial operation
Switching ON/OFF (Fig. A)
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 (Fig. A + E)
Connect all the electrical connections for the power
supply and for the welding current circuit. Most coated
electrodes are connected to the positive pole. Howev-
er, 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
(9/10) to the quick-lock couplings (6/7) accordingly.
Then fasten the unsheathed end of the elec-
trode 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 ig-
niting an arc. Check that you have the correct electrode
and current strength on a test part.
Note: See the following table for information on the
welding current to be used, depending on the electrode
diameter.
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
4,0 120 - 160 A
Important!
Do not dab the workpiece with the electrode since it
could be damaged, making it more difficult to ignite the
arc.
28 | GB
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°.
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 overheating. 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.
10. Electrical connection
The customer's mains connection as well as the
extension cable used must also comply with these
regulations.
Damaged electrical connection cable
The insulation on electrical connection cables is of-
ten damaged.
This may have the following causes:
•
Passage points, where connection cables are
passed through windows or doors.
•
Kinks where the connection cable has been improp-
erly fastened or routed.
•
Places where the connection cables have been cut
due to being driven over.
•
Insulation damage due to being ripped out of the
wall outlet.
•
Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
