MIG (GMAW)

Welding

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

Features	Benefits
Operates on open-circuit and arc voltages	Requires only the secondary weld cable to power feeder, no control cord needed.
Voltage-sensing control circuit with	Allows the feeder to be used with most constant-current and constant-voltage DC power sources.
CC/CV switch
S-32S wire speed range:	Accommodates a wide variety of wire sizes and types, .023 – 5/64 in (0.6 – 2.0 mm).
50 – 700 IPM (1.3 – 18 m/min)
S-32SL wire speed range:	Designed for 5/64– 7/64 in (2.0 – 2.8 mm) diameter wire.
25 – 325 IPM (0.6 – 8.2 m/min)
Polarity insensitive	Operates on straight (electrode negative) or reverse (electrode positive) polarity.
High-torque, 24 VDC drive motor with two	Offers excellent wire feeding performance and long uninterrupted service life.
gear-driven drive rolls
Solid-state speed control and brake circuit	Exceptional speed control and regulation; eliminates the need for electrical/mechanical relays and increases service life.
Overload protection	Protects motor and control circuit against possible damage due to overloading conditions.
Quick-change drive rolls and quick connect	No tools required. Easy attachment.
for Miller guns
Insulated gun-holding bracket	Convenient place for holding gun when not welding or when transporting the feeder.
