Simple to use but with all the features needed for
heavy-duty wire feed applications... that’s the S-32S
and S-32SL wire feeders from Miller. Built with the
strength and flexibility to handle the strenuous work
loads of field and fabrication shops, the S-32S and
S-32SL delivers proven reliability and performance.
These feeders operate off arc voltage, so a control
cord is not required. Operates with most CV and CC
DC-type power sources.
The S-32S and S-32SL handle the necessary highend speed for small diameter wires, and the lowend speed and
power for the more demanding larger
diameter wires.
Applications
Structural steel
Building construction
Bridge construction
Field maintenance and repair
Outdoor equipment repair and build-up work
(Use with CC/CV,
DC Power Sources.)

Requires only the secondary weld cable to power feeder, no control cord needed.
Allows the feeder to be used with most constant-current and constant-voltage DC power sources.
Accommodates a wide variety of wire sizes and types, .023 – 5/64 in (0.6 –2.0 mm).
Designed for 5/64– 7/64 in (2.0 –2.8 mm) diameter wire.
Operates on straight (electrode negative) or reverse (electrode positive) polarity.
Offers excellent wire feeding performance and long uninterrupted service life.
Exceptional speed control and regulation; eliminates the need for electrical/mechanical relays and increases service life.
Protects motor and control circuit against possible damage due to overloading conditions.
No tools required. Easy attachment.
Convenient place for holding gun when not welding or when transporting the feeder.

Gas Solenoid Valve
#093 768 Field
[ A: 15 ]
Required when using gas-shielded type wires.
Includes purge control. Operates off the arc
voltage and is designed for use with hot wire
set-up or when using an external secondary
contactor.
External Secondary Contactor
#108 921
[ A: 10 ]
Contactor rating:
400 amps at 30% duty cycle
330 amps at 60% duty cycle
250 amps at 100% duty cycle
Allows the welding wire to be electrically
cold until the operator is ready to weld. The
contactor can be used with direct current
(DC) power sources operating in either reverse
(electrode positive) or straight (electrode
negative) polarity. The contactor will operate
off 115 VAC or can be connected to a 12 VDC
battery of an engine driven welder not having
115 VAC auxiliary power available. The gun
trigger switch controls the contactor and must
remain closed while welding.
Note: 25 ft (7.6 m), #108 925, or 50 ft (15.2 m), #108 926,
remote contactor cord required.

the skill level required to install the option. The number
indicates the approximate time required for installation (see
legend).
A– Easy. No previous experience needed.
B– Average. Requires removal of service panels.
Mechanical ability is helpful.
C– Difficult. May require the use of an ohmmeter and/or
splicing of electrical wires. Repair or replacement of
component parts is more difficult.
