Feed the remote control cable through the box
connector on the case front, to provide a strain relief
for the cable. Connect the numbered leads in the
control cable to the like numbered terminals on the
right hand terminal strip (75 to 75, 76 to 76, and 77 to
77). Connect the green ground lead to the stud

Connection to Auxiliary Power
The DC-650 PRO has an extra 15 amps of 115 amp
VAC auxiliary power, above what is required for wire
feed equipment. This auxiliary supply is available on
terminals 33 and 34 on the terminal strip. This supply
is protected by a 15 amp circuit breaker.

Output Control Potentiometer
Controls the output of the machine. Adjusts
current when welding in the SMAW mode, and
adjusts voltage when welding in the GMAW,
FCAW and SAW modes. The Output Control
switch must be in the Local position for this
control to be active.
