The welding gun’s control cable is connected to the X7 socket (6*) and is secured by
turning the cap nut rightward. The control cable transfers the signals to the welding
gun controls.
Then the device is on, the yellow COIL control lamp (4*) lights up. When the release
button on the welding gun is pressed, the yellow START control lamp (3*) lights up.
During the welding process, the COIL control lamp (4*) goes off briefly. If this control
lamp does not light up at all, the welding gun’s magnetic coil circuit is defective. If the
START control lamp (3*) does not light up when the welding gun is activated, the
trigger current circuit is defective (
see Chapter 8.2 “Troubleshooting”).
4.3 Earth cable connection
The weld current return goes through the two earth cables, which must be connected
to the INTRA 2100/1400 welding device as follows:
Earth cable plug connections:
The earth cables’ plugs must be connected to the two
sockets marked X21
(
see Pos. 5 in the illustration on page 24).
The connections must be secured by strongly pressing
rightward to the stop.
Earth cables and earth clamps are not delivered with the INTRA 2100/1400.
Warning:
•
The earth cable connections cannot be locked! The connection
must be tested regularly for tightness!
•
To prevent inductive shunts, the earth cables must be laid
without looping, to the degree possible.
