A12 — Questions to Check Before Ordering.
Is A12 only for plasma?
A12 is designed around plasma and flame cutting work with arc-voltage control, cylinder delay and Z-axis isolation. It can also run general 3-axis jobs, but plasma-specific control is its reason to exist.
What makes A12 stronger against interference?
The design targets electrically noisy cutting environments with Z-axis isolation and repeated CE anti-jamming tests.
Can A12 replace a standard 3-axis router controller?
Yes for basic 3-axis work, but for a router-only machine you can often use a simpler controller. Verify the wiring board and signals before deciding.
Which documents should I send for an A12 quote?
Send the machine type, current controller, torch configuration and any wiring references so CINKR can confirm the correct configuration.
