A220 Fault Workflow Router

This router gives the fastest document order for the highest-value A220 complaints.

Complaint Routing

Incoming complaint	Open first	Then open	Then open if the complaint remains	Why this order works
machine feels weak only on generator or long cord	A220 measurement card	A220 parts substitution card	A220 guide	utility-path proof belongs ahead of deeper opening
rod behavior is poor but power-up looks normal	A220 measurement card	A220 board opening map	A220 guide	normal OCV with poor rod behavior still belongs to current-path proof first
clamp, holder, or plug heats quickly	A220 parts substitution card	A220 guide	A220 job packet	hot current-path hardware is still the fastest external branch to clear
utility and current path are proven but output is still weak	A220 measurement card	A220 board opening map	A220 job packet	once externals are proven, the route shifts cleanly into the output branch
arc feels wrong after lead service or setup change	A220 parts substitution card	A220 measurement card	A220 guide	polarity and high-load rod proof still belong before internal opening

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.

Stop Rules

Stop if a stronger source or shorter cord changes the complaint.
Stop if correct polarity and known-good 7018 or 6010/6011 proof rod remove the complaint.
Stop if the machine is being routed as TIG, because A220 is officially not recommended for TIG welding.
Stop if current-path heating clearly explains the failure.
Stop and move to the full guide if utility, current-path, and output evidence still overlap after the first pass.
