CoolCut40air Measurement Card

This is the quick live-reading card for the highest-value CoolCut40air internal-air, external-air, and valve-branch splits.

Use This Card When

the complaint exists only in one air mode
both air paths seem to move together
cut quality is poor and the air package is still suspicious

Prove First

fresh SG55 front-end stack
dry external air source if that mode is used
clean clamp path on bright metal

Fast Measurement Card

Checkpoint	Where to measure or observe	Healthy expectation	If abnormal, keep diagnosis in...
Internal-air trigger test	air delivery during trigger in internal mode	internal path only, no abnormal rear-inlet flow	compressor or internal-valve branch
External-air trigger test	air delivery during trigger in external mode	stable external path only	hose or external-valve branch
Dual-air behavior	compare internal and external responses	both paths do not flow together unless the fault is present	control-valve branch
Start and transfer	start attempt on clean steel	stable start and transfer with the correct air path	torch-front-end or air-package branch

Official Parts Shortcuts

Use these only after the readings prove the complaint follows the torch-front-end or air-package branch.

Stop if the complaint exists in only one air mode.
Stop if moisture or front-end correction changes the complaint immediately.
Stop using the card and open the full guide if mode split, valve behavior, and output evidence still conflict.
