Switching between Push/Pull and intermediate drive
WARNING
Do not carry out any unauthorised repairs or modifications!
To avoid injury and equipment damage, the unit must only be repaired or modified by
specialist, skilled persons!
The warranty becomes null and void in the event of unauthorised interference.
• Appoint only skilled persons for repair work (trained service personnel)!
The wire feeder used in the welding system has to be modified for use with an intermediate drive. To do
so, unscrew the casing cover and perform the following two actions on PCB M370/1:
Replug the connector (X23/X24)
Plug
Function
On X24
Use with push/pull welding torch (ex factory)
On X23
Use with intermediate drive
Install cable adapter
The cable adapter (included with the intermediate drive) has to be added to the wire feeder cable
harness.
The cable adapter has to be plugged in at three locations (X2, X3 and X5) between the relevant PCB
connections and cable plugs (see attached circuit diagram
> see 11.1 chapter
):
• PCB M370/1, connection X2 (18-pole)
• PCB M370/1, connection X3 (2-pole)
• PCB M370/1, connection X5 (12-pole)

Test!
Before re-commissioning, it is essential that an "inspection and test during operation" is carried
out conforming to IEC / DIN EN 60974-4 "Arc welding devices - inspection and testing during
operation"!
• For detailed instructions, please see the standard operating instructions for the welding
machine.
