TIG200PACDC Measurement Card

This is the quick live-reading card for the highest-value TIG200PACDC DC-versus-AC, gas, and pedal-branch splits.

Use This Card When

DC TIG and AC TIG do not behave the same
the complaint may follow the pedal branch
shielding-flow behavior still looks suspicious

Prove First

correct torch front end and tungsten
known-good gas regulator and hose path
plain DC TIG baseline before AC or pulse proving

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 AC or pulse is added back	gas, torch, or TIG-only branch
AC TIG baseline	live start in AC mode	stable AC behavior once DC is already healthy	AC-mode branch
Pedal response	current response while pedal is connected	current changes only with the correct pedal branch	pedal or remote branch
Gas-flow behavior	regulator and torch during start	stable shielding flow	gas hose or regulator branch

Official Parts Shortcuts

Use these only after the readings prove the complaint follows the gas or remote-accessory branch.

Stop Rules

Stop if the complaint follows one pedal only.
Stop if DC TIG is healthy and only AC remains faulty.
Stop using the card and open the full guide if gas, AC, and pedal branches still conflict.
