How do I use the Auto-Set feature on the Millermatic 211?

To use Auto-Set, turn the wire speed control into the blue/green zone that corresponds to your wire diameter — the Auto-Set indicator light will illuminate. Then turn the voltage control to the blue/green zone matching the material thickness you are welding, and the machine will automatically set the appropriate voltage and wire feed speed. Blue zones are for 0.035-inch wire and green zones are for 0.030-inch wire. (Page 21)
