Mild Steel Welding Capability
Not to scale.


Min. — 24 ga (.8 mm)

Max. — 5/16 in (7.9 mm)

New! Auto-Set™ is a breakthrough control that automatically sets your welder to the proper parameters. Auto-Set offers all-in-one MIG, minus the guesswork!

Welds thickest material in its class, with the highest output in its class! Can weld up to 5/16 inch in a single pass.

New spool gun compatible! Finally a reliable and economical way to weld aluminum. Hooked up to a Millermatic 180 or 180 with Auto-Set, the new Spoolmate 100 Series spool gun allows you to weld from 18 gauge to 1/4 inch aluminum.

Manual Mode has the flexibility to manually set weld parameters for broader applications.

New! Smooth-Start™ patent-pending technology provides a smooth, spatter-free start. —The best starting machine in the small MIG category.  No pop-gun starts or spatter to clean up.

Durable cast aluminum feedhead incorporates dual groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob all designed to make setup easier and faster.

Thermal overload protection shuts down the unit and activates over temperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when fault is corrected and unit cools.

Miller's exclusive "Tip Saver" short circuit protection shuts down output when tip is shorted to the work. Extends contact tip life and protects internal components from damage. Trigger reset permits quick reset at torch rather than unit.

Standard built-in solid-state contactor circuit makes wire electrically "cold" until trigger is pulled. Makes unit safer, and is easier to position torch to work before starting weld.

Easy access to output studs provides convenient polarity changeover when switching from solid or flux cored wires.

Self-resetting motor protection circuit eliminates the need to find and replace fuses.

Uses 4 or 8 in (102 or 203 mm) spools and can be set up to weld with wire sizes .024-.035 in (0.6-0.9 mm) mild/stainless steel and .030-.045 in (0.8-1.2 mm) flux cored.
