PulseWave200 Parts Substitution Card

This is the quick external-parts substitution card for the highest-value PulseWave200 TIG accessory and control-path splits.

Use This Card When

TIG will not start and the complaint may still be torch or remote related
only one pedal, remote, or wireless control path misbehaves
the panel is strange after an arc event but the accessory branch is still in play
the machine has not yet been reduced to simple DC TIG with local control

Stage First

known-good base TIG torch on negative
known-good one-control-device-only path: FC25-HD, FC25-WL, or YK25-WL
known-good gas-path setup with realistic low-current flow
simple DC TIG baseline with local control and pulse-like features stripped out

Fast Substitution Card

Complaint branch	Swap first	If the complaint follows the part...	If the complaint stays with the machine...
no TIG start with a torch or remote connected	known-good base TIG torch on negative with no optional control branch and simple DC TIG baseline	keep diagnosis in the torch or connected accessory	move to stored-state, gas-flow, and AC/DC branch logic
complaint exists only with one pedal or remote	known-good single control device, one at a time	keep diagnosis in that remote branch	move into the main machine only if local or base-torch operation still fails
unstable low-current start	corrected gas setup and known-good torch front end	keep diagnosis in gas or torch path	move deeper only if the basic TIG baseline still fails

Stop Rules

Stop if the complaint disappears with the base torch and no optional control attached.
Stop if a stored-state reset clears the symptom before the substitution path is complete.
Stop if simple DC TIG with local control is healthy and only one pedal or remote branch still fails.
Stop using the card and open the full guide if the machine still fails with a stripped-down base TIG setup.
