An optional “remote out control” is available. The
K775 is the same remote control that is used on other
Lincoln power sources. The K775 consist of a control
box with 28 feet (8.5mm) of four conductor cable. This
connects to terminals 75,76, and 77 on the terminal
strip (T.S.1) and the case grounding screw so marked
with the symbol “ ” on the machine. These termi-
nals are located behind the hinged cover on the case
front. This control will give the same control as the
output control on the machine.
The K857 is similar to the K775, except the K857 has
a 6-pin MS-style connector. The K857 requires a
K864 adapter cable which connects to the 14-pin con-
nector on the case front.

feeder connection is then not used.

The MULTI-PROCESS SWITCH gives you the ability
to:
• Switch between "stick welding or air/carbon arc cut-
ting" and using a semi-automatic or automatic wire
feeder.
• Change the polarity of a semi-automatic or auto-
matic wire feeder without changing any electrical
cable connections.
