Initial Operation; Electrical Connection - Scheppach WSE1100 Original Bedienungsanleitung

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.

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. Electrical connection

The electrical motor installed is connected and
ready for operation. The connection complies
with the applicable VDE and DIN provisions.
The customer's mains connection as well as
the extension cable used must also comply with
these regulations.
Damaged electrical connection cable
The insulation on electrical connection cables is of-
ten damaged.
This may have the following causes:
Passage points, where connection cables are
•
passed through windows or doors.
Kinks where the connection cable has been im-
•
properly fastened or routed.
Places where the connection cables have been cut
•
due to being driven over.
• Insulation damage due to being ripped out of the
wall outlet.
Cracks due to the insulation ageing.
•
Such damaged electrical connection cables must not
be used and are life-threatening due to the insula-
tion damage.
Check the electrical connection cables for damage
regularly. Make sure that the connection cable does
not hang on the power network during the inspection.
Electrical connection cables must comply with the
applicable VDE and DIN provisions. Only use con-
nection cables with the marking „H05VV-F".
The printing of the type designation on the connec-
tion cable is mandatory.
AC motor
The mains voltage must be 230 V~
•
Extension cables up to 25 m long must have a
•
cross-section of 1.5 mm2.
Connections and repairs of electrical equipment
may only be carried out by an electrician.
