This is the quick live-reading card for the highest-value MultiSonic220 control-state and MIG-only branch splits.
| Checkpoint | Where to measure or observe | Healthy expectation | If abnormal, keep diagnosis in... |
|---|---|---|---|
| Startup state after reset | panel behavior after documented reset | machine exits debug behavior and boots normally | stored-state, ribbon, or support-power branch |
| Polarity connector | machine front current path for MIG | tight and correctly installed when MIG is selected | polarity and MIG-only current-path branch |
| Panel behavior at power-up | live observation | stable display and indicators, not full flash or Christmas-tree behavior | ribbon, control, or power-supply branch |
| Feeder motor at idle | motor behavior with no trigger command | feeder remains stopped until commanded | power board or support-power branch if motor runs full speed |
