5. Welding preparations
Connect the earth terminal (-) (2) direct to the part
to be welded or to the support on which the part is
resting. Ensure that the earth terminal (-) is in di-
rect contact with the part to be welded. You should
therefore avoid coated surfaces and/or insulated
materials. The electrode holder cable has a spe-
cial 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 (not
included in items supplied).
6. 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 (1) and connect the earth ter-
minal (-) (2) to the part you wish to weld.
Ensure that a good electric contact is made.
Switch on the welding set at the switch (4) and set
the welding current using the hand wheel (3) to
suit the electrode you wish 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 that you have the correct electrode and
current strength on a test part.

1,6................................................................. 40 A
2 ............................................................ 40 - 80 A
2,5 ....................................................... 60 - 100 A
Important!
Do not dab the workpiece with the electrode since
it could be damaged, making it more di ffi cult 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 pos-
sible during the welding process. The angle of the
electrode in the direction in which you are working
should be 20/30°.
