Miller Electric S-32S User Manual
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.)

Insulated gun-holding bracket
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.
