CoolTIG220 Measurement Card

This is the quick live-reading card for the highest-value CoolTIG220 gas, control-branch, and version-path splits.

Use This Card When

there is no TIG start
the complaint may follow one remote or switch branch
the machine may be treated like the wrong HF or no-HF version

Prove First

correct torch front end and tungsten
known-good gas regulator and hose path
simple DC TIG baseline before pulse or optional controls

Fast Measurement Card

Checkpoint	Where to measure or observe	Healthy expectation	If abnormal, keep diagnosis in...
DC TIG baseline	live start on clean steel	repeatable start before advanced settings are added back	torch, gas, or version branch
Gas-flow sequence	regulator and torch during preflow and postflow	stable flow without obvious leak or collapse	regulator, hose, or torch-front-end branch
Torch-switch or remote branch	live control response	only the intended branch changes the machine state	switch, remote, or pedal branch
Stick branch if used	simple stick weld	stable output after TIG baseline is proven	TIG-only branch if stick stays healthy

Stop Rules

Stop and keep the diagnosis external if the complaint follows one remote or switch branch only.
Stop if gas-path correction changes the complaint immediately.
Stop using the card and open the full guide if gas, version, and control evidence still overlap.
