FX650XL
Control - Local/Remote Toggle Switch
• Set the switch to "local" to control output at the FX650XL via
the Output Control dial.
• Set the switch to "remote" to control output via a remote
device (K857-2 hand amptrol or K870-2 foot amptrol)
connected to the 12-pin remote connector or a wire feeder
connected to the 14-pin connector.
Wire Feeder Voltage Selector Switch
• This switch configures wire feeder supply voltage in the 14
pin connector to either 42 volts or 115 volts.
• If the switch is in the incorrect position for the attached wire
feeder, there will be no power supplied to the wire feeder.
Wire Feeder Voltmeter Polarity Switch
• This switch configures the 21 sense lead in the 14 pin
connector to the work weld terminal of the machine. It also
configures the 292 lead to the User Interface board to
determine if voltage sensing needs to be configured for
Electrode Negative Polarity operation in "ArcLink" mode.
Thermal Light
• This status light indicates when the power source has been
driven into thermal overload. If the output terminals were
"ON", the output will be turned back on once the unit cools
down to an acceptable temperature level. If the unit was
operating in the "REMOTE" mode, the trigger will need to be
opened before or after the thermal has cleared and closed
after the machine has cooled down to an acceptable
temperature to establish output.
VRD™ (VOLTAGE REDUCTION DEVICE) INDICATOR LIGHT
• There are 2 indicator lights on the case front of the
FX650XL above the Voltage LED Display to indicate the status
of VRD™ operation. As shipped, the VRD™ function is
disabled. VRD™ is enabled by setting dip switches on the
Control P.C. board (See Internal Controls Figure B.3 in this
Operation Section). When VRD™ is active:
• A green light indicates the OCV (open circuit voltage) is less
than 35V peak.
• A red light indicates the OCV is at or above 35V peak.
• Both lights will illuminate for 5 seconds at power up.
For each weld mode, the VRD™ lights function as shown in Table
B.1:

CC-SMAW
CC-GTAW
CV-GAS
CV-Innershield
CV-SAW
* It is normal for the lights to alternate between colors while welding.

bASIC mODES OF OPERATION
SMAW
This weld mode is a constant current (CC) mode featuring
continuous control from 15 – 815 amps. It is intended for the
SMAW stick welding processes and arc gouging.
Output Control Local/Remote – When the control is set to "local"
(no remote potentiometer/control plugged into the 12 pin or 14 pin
connectors), the output is controlled through the Output Control
Dial on the front of the FX650XL. Set this switch to "Remote"
when an external potentiometer/control is connected.
• When a remote potentiometer is connected, the output control
on the FX650XL and the remote act as a master/slave config-
uration. Use the control dial on the FX650XL to set the
maximum welding current. The remote will control output
from minimum to the pre-set maximum.
Hot Start - The Hot Start control regulates the starting current at
arc initiation. Hot Start can be set to "0" and no additional current
is added at arc start. Increasing from 0 to 10 will increase the
additional current (relative to the preset current) that is added at
arc initiation.
Arc Control - The Arc Control regulates the Arc Force to adjust
the short circuit current. The minimum setting (-10) will produce a
"soft" arc and will produce minimal spatter. The maximum setting
(+10) will produce a "crisp" arc and will minimize electrode
sticking.
Weld Terminals On/Remote – Set to "On" and the machine is in
the ready to weld state.
Voltage Display Meter – This display will display three dashed
lines when the machine is in the idle state. This indicates that
voltage is not settable in this weld mode. While output is enabled,
the actual welding voltage will be displayed. After welding, the
meter holds the actual voltage value for 5 seconds. Output
adjustment while in the "hold" period results in the "prior to
operation" characteristics stated above. The displays blink
indicating that the machine is in the "hold" period.
