CoolArc200 Fault Workflow Router

This router gives the fastest document order for the highest-value CoolArc200 complaints.

Complaint Routing

Incoming complaint	Open first	Then open	Then open if the complaint remains	Why this order works
machine reads the wrong input class	CoolArc200 measurement card	CoolArc200 board opening map	CoolArc200 guide	the real input and J3 split should be proven first, then the opening map keeps the work inside the main-board versus control-board branch
low OCV that may just be mode behavior	CoolArc200 measurement card	CoolArc200 job packet	CoolArc200 board opening map	the measurement card separates normal `VRD` or wake-up behavior before the packet and internal map are needed
blink-only startup or no-fan behavior	CoolArc200 measurement card	CoolArc200 parts substitution card	CoolArc200 board opening map	fan and startup complaints should stay external until the fan path is bounded cleanly
TIG-only complaint	CoolArc200 parts substitution card	CoolArc200 guide	CoolArc200 job packet	the official TIG kit and gas path still come before internal repair on this model

Official Parts Exit Paths

If the complaint proves external at any point in the router, use the official parts flow instead of continuing into board work.
CoolArc200 parts category: official parts path
TIG kit 07003750: official product page
230 V to 125 V adapter 07001825: official product page
Ground clamp 07000462: official product page

Stop Rules

Stop if VRD or first-weld wake-up behavior explains the low OCV complaint.
Stop if the actual input or adapter path explains the wrong input-class complaint.
Stop if the complaint follows the TIG kit or fan branch.
Stop and move to the full guide if the J3 reading and panel behavior still conflict after the first pass.
