CONTROLS AND SETTINGS

All operator controls and adjustments are located on the case front of the CV-655. Refer to Figures B.1, and B.2
and corresponding explanations.
1. INPUT POWER ON/OFF SWITCH - This tog-
gle switch turns the machine on or off. Putting the
switch in the ON
machineʼs input contactor applying input power to
the machine. Switching the switch to the
OFF position de-energizes the input contactor.
2. PILOT LIGHT - When the power switch is in the
ON position the machineʼs white pilot light will illu-
minate. If the input contactor de-energizes the
machine in an overload situation the pilot will still
illuminate. In this situation it will be necessary to
reset the machine by switching the power switch to
the OFF then ON position. (See Overload
Protection Section)
3. OUTPUT VOLTAGE CONTROL - This control
provides continuous control of the machineʼs output
voltage from minimum to maximum (typical full pot
range between 15 to 44 volts) as it is rotated clock-
wise.
4. OUTPUT TERMINALS ON/REMOTE - When this
switch is in the REMOTE
output terminals will be electrically "cold" until a
remote device such as a wire feeder closes the #2
and #4 circuit in the MS-receptacle or terminal strip.
When this switch is in the ON position the

5. LOCAL/REMOTE CONTROL SWITCH - When this
switch is set to the LOCAL
the output voltage is via the output voltage control
on the CV-655ʼs control panel. When this switch is
set to the REMOTE
a remote source such as a wire feeder via the #75,
#76, and #77 leads in the MS-receptacle or terminal
strip.
6. THERMAL PROTECTION LIGHT
machine overheats due to lack of proper air flow
through the machine or due to exceeding the
machineʼs duty cycle, thermostats will disable the
welding output and this light will illuminate. Input
power is still applied to the machine and the cooling
fan will continue to run.
the welding output will resume.
7. OPTIONAL VOLTMETER & AMMETER - Digital
or analog meter kits are available as field installed
