5. Optional Remote Control (K775)
This control is included as part of the “NL Option”.
Connect it to the “NL Option” box per instructions
shipped with the option. (Not required with the NA-
3, NA-5, LT-7 or LT-56.)
It can be purchased separately when the DC-1500
is used for other applications.
To install, turn the power off. Remove the screw
and lift the hinged door on the front of the control
panel to expose the terminal strips. Connect the
numbered leads to the appropriate terminals — 75
to 75, etc — on the terminal strip and the green
lead to the stud marked with the symbol .
Attach the control cord to the panel at the right of
the terminal strip using a suitable clamp. Close the
door and replace the screw. The Re-mote Control
cord can be lengthened to any length by properly
splicing an appropriate four conductor rubber-cov-
ered cable to the standard 25’ cord before connect-
ing to the DC-1500 terminal strip.
6. Connecting for Air Carbon Arc
To use the DC-1500 for air carbon arc or other
appli-cations, disconnect all wire feeder welding
cables and control leads and connect a jumper
between #2 and #4 on the terminal strip on the front
of the DC-1500. With the #2 to #4 jumper connect-
ed, the output studs are en-ergized whenever the
machine is on.
If the electrode leads to the wire are not discon-
nected per instructions, the wire feeder nozzle or gun
and electrode will be electrically “hot”.
