Power Switch; Run-In Setting - Miller Electric Millermatic 212 Auto-Set Owner's Manual

5-2. Power Switch

5-3. Run-In Setting

Run-In is the speed of the wire prior to the welding arc being struck. This setting is a percentage of the wire feed speed
the unit is set to for welding. Programming values range from 25 − 100%.
The standard MIG gun has a separate Run-In from the Spoolmatic 15/30A spool gun. Both Run-Ins are set to 50%
from the factory for optimal arc starts.
To adjust run-in, first turn off the unit. While the unit is off, pull the trigger on the gun that is going to be adjusted, then
turn on the unit. The yellow OVERTEMP light will flash once indicating a trigger error. Turn the wire speed control to
minimum, then turn the wire speed control to maximum. The yellow light will turn off and the Auto-Set light will flash
indicating that Run-In is now settable. Turn the wire speed control to the desired percentage. For example, setting the
wire speed control to 60 will set the run-in percentage to 60%. Finally, release the trigger to save the run-in setting.
