5. Installation Instructions
Assembling the welding screen (Fig. 2-5)
Insert the safety glass (10) and then the
welding glass (11) in the welding screen (9).
Now fasten the welding screen holder (12) to
the welding screen, as shown in Fig. 5.
6. Mains connection
Before you connect the equipment to the
mains supply make sure that the data on the
rating plate are identical to the mains data.
7. Welding preparations
Connect the earth terminal (4) directly 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 screen (9) 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
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
hand 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.
Electrode (Ø mm): Welding current (A)
1.6 40
2 40-80
2.5 60-100
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
must be kept as constant as possible during
the welding process. The angle of the
electrode in the direction in which you are
working must 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.
9. 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.
