Millermatic® 180 Auto-Set™
All-in-one wire welder that welds 24 gauge - 5/16 in. (0.8 - 7.9 mm) mild steel.
Auto-Set™
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 in. in a single pass.
Smooth-Start™
This 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.
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. See how it works.
Spool Gun Compatible!
Finally a reliable and economical way to weld aluminum. Hooked up to a 180 Auto-Set, the Spoolmate 100 Series spool gun allows you to weld from 18 gauge to 1/4 in. aluminum.
Manual Mode
Gives you the flexibility to manually set the machine when welding aluminum, stainless steel or anytime you want to set your own parameters on mild steel.
Durable Cast Aluminum Drive System
Incorporates dual groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob all designed to make setup easier and faster.
'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. See how it works.
