Electrical Connection; Maintenance And Cleaning - Scheppach WIG2000-Multi Original Bedienungsanleitung

To continue a weld on an interrupted seam:
• First remove the slag at the connection point.
• The electric arc is struck in the weld groove, guided
to the connection point, properly melted there and
then continued along.
m Attention! The welding work generates heat. There-
fore, the welder must be left idle for at least half an hour
after use. Alternatively, let the device cool down for one
hour. The device must not be packed and stored until
its temperature has normalised.
m Attention! A voltage that is 10% lower than the rat-
ed input voltage of the welding machine can lead to the
following consequences:
• The current of the unit decreases.
• The arc breaks off or becomes unstable.
m Attention!
• The arc radiation can cause eye inflammation and
skin burns.
• Spray and molten slag can cause eye injuries and
burns.
Only welding cables that are included in the scope of
delivery may be used.
Choose between forward-pointing welding and draw
welding.
The influence of the direction of movement on the prop-
erties of the weld seam is shown below:

11. Electrical connection

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:
•
Pressure points, where connection cables are
passed through windows or doors.
•
Kinks where the connection cable has been improp-
erly 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 insulation
damage.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables with the designation H05RR-F.
The printing of the type designation on the connection
cable is mandatory.
•
The mains voltage must be 230 V~
•
Extension cables up to 25 m long must have a
cross-section of 2.5 mm2.
Connections and repair work on the electrical equip-
ment may only be carried out by electricians.

of any enquiries:

12. Maintenance and cleaning

Danger!
Disconnect the mains plug before carrying out any
cleaning work.
Note: The welding machine must be serviced and
overhauled regularly to ensure proper operation and
compliance with safety requirements. Improper and
incorrect operation may result in failure and damage
to the device.
• Before carrying out any cleaning work on the weld-
ing machine, pull the mains cable out of the socket
so that the device is safely disconnected from the
power supply circuit.
• Clean the outside of the welding device and its ac-
cessories regularly. Remove dirt and dust using air,
a cleaning rag or a brush.
Note: The following maintenance work shall be carried
out only by qualified specialists.
• Current regulator, earthing device, internal wiring,
the welding torch coupling device and adjustment
screws should be serviced regularly. Retighten
loose screws and replace rusty screws.
