Ensure that a good electric contact is made. Switch on the device and set the welding cur-
rent, depending on the electrode used, using the potentiometer (11). 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 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):
1.6
2
2.5
3.2
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°.
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.
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 (12) 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.
