Overheating guard
The welding set is fitted with an overheating guard
that protects the welding transformer from overheat
-
ing. 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 af-
ter-sales service or similarly trained personnel to
avoid danger.
10. Cleaning
Danger!
Always pull out the mains power plug before starting
any cleaning work.
Cleaning
•
Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
•
We recommend that you clean the device immedi-
ately each time you have finished using it.
•
Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts of
the equipment. Ensure that no water can seep into
the device. The ingress of water into an electric tool
increases the risk of an electric shock.
11. Transport
For easy transport of the welding machine, carry it
over the shoulder using the carrying strap provided
or simply carry by the transport handle.
12. Storage
Store the device and its accessories in a dark, dry
and frost-proof place that is inaccessible to children.
The optimum storage temperature is between 5 and
30˚C.
Store the electrical tool in its original packaging.
Cover the electrical tool in order to protect it from dust
and moisture.
Store the operating manual with the electrical tool.
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 coat-
ed electrodes are connected to the positive pole.
However, some types of electrode have to be con-
nected to the negative pole. Ensure that you observe
the information supplied by the manufacturer in rela-
tion 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 electrode 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
igniting an arc. Check that you have the correct elec-
trode and current strength on a test part.
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.
As soon as the arc has ignited, attempt to keep it a
distance from the workpiece equivalent to the diame
-
ter of the electrode.
This distance should be kept as constant as possible
during the welding process. The angle of the elec
-
trode 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.
