CoolTIG220 Fault Workflow Router

This router gives the fastest document order for the highest-value CoolTIG220 complaints.

Complaint Routing

Incoming complaint	Open first	Then open	Then open if the complaint remains	Why this order works
no TIG start with otherwise normal idle state	CoolTIG220 measurement card	CoolTIG220 parts substitution card	CoolTIG220 board opening map	the fastest path is simple DC TIG plus gas and torch proof first, then the opening map only if the complaint stays internal
machine behaves like the wrong HF or no-HF version	CoolTIG220 measurement card	CoolTIG220 board opening map	CoolTIG220 guide	version proof belongs ahead of deeper board work
stick works but TIG still fails	CoolTIG220 measurement card	CoolTIG220 board opening map	CoolTIG220 job packet	process split comes first, then the opening map keeps the work inside the TIG branch
complaint follows one switch or pedal branch	CoolTIG220 parts substitution card	CoolTIG220 guide	CoolTIG220 job packet	control-accessory complaints still belong outside the machine first, with local control proven before any teardown

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 the complaint follows one control branch only.
Stop if gas correction restores the machine.
Stop if the fitted unit matches the documented no-HF version note and the supposed HF fault disappears under the right expectation.
Stop and move to the full guide if version, gas, and control evidence still overlap after the first pass.
