Machine concept
KD Supply 2500
The KD Supply 2500 enables the TIG
power sources TT 2500 / 3000 Job and
MW 2500 / 3000 Job to be used with a
cold wire feeder. The built-in switched-
mode power supply supplies the feeder
motor.
The KD Supply 2500 simultaneously func-
tions as an active LocalNet distributor. In
addition to providing an interface to the
cold wire feeder, the KD Supply 2500 also
has an additional LocalNet interface, e.g.
for a remote control unit.

Fitting the KD Supply 2500 to the trolley
General remarks The welding system can be fitted to a trolley to increase the mobility of the system.
IMPORTANT!
If the welding system is not equipped with an auto-transformer or a cooling unit,
the KD Supply 2500 must be installed right at the bottom.
- If a cooling unit is present, fit it right at the bottom and place the KD Supply on top of
it.
Fitting the KD
Supply 2500 to
the base of the
trolley
1If there are no fastening brackets on
the trolley:
Attach two fastening brackets to the
base of the trolley and secure each
one using three „Extrude-Tite“ screws.
2Place the KD Supply 2500 on the
base of the trolley.
3Using „Extrude-Tite“ screws, fasten
the KD Supply 2500 at the front and
back to the fastening brackets on the
base of the trolley.
