Fcaw (Flux-Cored) Operation; Saw (Submerged Arc) Operation - Lincoln Electric DC-650 PRO IM463-A Operator's Manual

FCAW (Flux-Cored) Operation

Properly connect a wire feeder control cable to either
the terminal strip or to the Wire Feeder Receptacle.
If welding electrode positive, connect the electrode to
the "+" output studs, and connect the work cable to
the "-" studs labeled "GMAW, FCAW". If welding
electrode negative, reverse the connections. Do not
make any connections to the left hand pair of output
studs.
Set the control panel switches as follows:
------------------------------------------------------------------------
Mode: FCAW
------------------------------------------------------------------------
Output Local or Remote (See "Output Control
Control: Switch")
------------------------------------------------------------------------
LN-9/NA-5: Off, unless an LN-9 or NA-5 is being
used.
------------------------------------------------------------------------
Wire Feeder Set to match the electrode polarity.
Voltmeter:
------------------------------------------------------------------------
Output
Terminals: Remote
------------------------------------------------------------------------
If using Local output control, preset the desired
welding voltage using the Output potentiometer and
the voltmeter. If using Remote Output control, preset
the welding voltage using a remote control, or with the
voltage control on the wire feeder. If using an LN-9
and NA-5, see "operation with LN-9 or NA-5 Wire
Feeder" section.
Set up the wire feeder according to the wire feeder
instruction manual.
When the gun trigger is pulled (or the weld sequence
is started) and an arc is struck, the voltmeter will
display the welding voltage present at the output studs
of the DC-650 PRO, and the ammeter will display the
output current.

SAW (Submerged Arc) Operation

Properly connect a wire feeder control cable to either
the terminal strip or to the Wire Feeder Receptacle.
If welding electrode positive, connect the electrode
cable to the "+" output studs, and connect the work
cable to the "-" studs labeled "SMAW,SAW". If
welding electrode negative, reverse the connections.
Do not make any connections to the center pair of
output studs.
Set the control panel switches as follows:
------------------------------------------------------------------------
Mode: SAW
------------------------------------------------------------------------
Output Local or Remote (See "Output Control
Control: Switch")
------------------------------------------------------------------------
LN-9/NA-5: Off, unless an LN-9 or NA-5 is being
used.
------------------------------------------------------------------------
Wire Feeder Set to match the electrode polarity.
Voltmeter:
------------------------------------------------------------------------
Output
Terminals: Remote
------------------------------------------------------------------------
If using Local output control, preset the desired
welding voltage using the Output Potentiometer and
the voltmeter. If using Remote output control, preset
the welding voltage using a remote control, or with the
voltage control on the wire feed unit. If using an LN-9
or NA-5, see "Operation with LN-9 or NA-5 Wire
Feeder " section.
Set up the wire feed unit according to the wire feeder
instruction manual.
When the gun trigger is pulled (or the weld sequence
is started) and an arc is struck, the voltmeter will
display the welding voltage present at the output studs
of the DC-650 PRO, and the ammeter will display the
output current.
