5. Assembling the welding
screen (fig. 2-5)
Insert the safety glass (9) and then the welding
glass (10) in the welding screen (8). Now fasten
the welding screen holder (11) to the welding
screen, as shown in fig. 5.
6. Welding preparations
Connect the earth terminal (4) 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 (electrode holder (5)) at
one end, which is used to secure the electrode.
The welding screen (8) 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.
7. Welding
After you have made all the electrical
connections for the power supply and for the
welding circuit, you can proceed as follows:
Insert the unsheathed end of the electrode into
the electrode holder (5) and connect the earth
terminal (4) to the part you wish to weld. Ensure
that a good electric contact is made.
Switch on the welding set at the ON/OFF switch
(3) and set the welding current using the setting
wheel (6) to suit the electrode you wish to use.
Hold the welding screen 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.

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°.
Important!
Always use tongs to remove spent electrodes
and to move parts that you have just welded.
Please note that the electrode holder (5) 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.
8. 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 (7) on your set will be lit. Allow
the welding set to cool for a time.
9. Transport
Before transporting the welder you must first
disconnect the power plug and remove the
ground terminal from the workpiece. Then wind
up the cable properly. Now you can carry the
welder to a different place by the carry handle
(1).
