PulseWave200 Measurement Card

This is the quick live-reading card for the highest-value PulseWave200 TIG start and mode-state splits.

Use This Card When

TIG will not start or feels dead
AC TIG is dead while DC TIG still works
the display behaves strangely after an arc event

Prove First

torch on negative for TIG start
simple DC TIG baseline with local control
clean gas path and realistic low-current gas flow

Fast Measurement Card

Checkpoint	Where to measure or observe	Healthy expectation	If abnormal, keep diagnosis in...
Torch polarity for HF start	front output connections	torch on negative for TIG start	setup branch before any HF-board call
Display PCB switch `2` reset	later-machine display board	factory defaults restore when the switch is used with power off and the machine restarts	stored-state or display-state branch
Gas flow at very low current	torch and regulator behavior during low-current TIG setup	moderate flow with reduced preflow as needed for low-current work	gas-path setup before blaming a dead HF section
AC versus DC TIG behavior	practical weld test after baseline setup	both operate once the base machine is healthy	AC inverter section if DC works but AC does not

Official Parts Shortcuts

Use these only after the symptom is proven to follow the torch or remote branch rather than the AC or DC power stage.

Stop Rules

Stop and correct polarity or gas setup first if the no-start complaint disappears under a simple DC TIG baseline.
Stop and restore defaults first if the panel corruption clears with the documented reset.
Stop using the card and open the full guide if the machine passes DC TIG cleanly but still shows a mixed AC and control symptom.
