MultiSonic220 Parts Substitution Card

This is the quick external-parts substitution card for the highest-value MultiSonic220 process and accessory splits.

Use This Card When

MIG is dead while stick or TIG still works
the complaint follows only one process kit
a spool-gun, remote, or TIG kit may be the real fault path
stored state or hidden debug mode may still be the real issue

Stage First

known-good NT1-3E euro-end MIG torch with plain-steel baseline
known-good polarity connector seating for the active process
known-good SpoolKing-24DL spool-gun branch or known-good base-machine MIG branch
known-good PRO17 torch and one remote branch only for TIG complaints
documented 2T/4T reset and stripped-down base-machine state before blaming accessories

Fast Substitution Card

Complaint branch	Swap first	If the complaint follows the part...	If the complaint stays with the machine...
MIG-only no output or poor arc	known-good plain MIG torch and confirmed polarity connector	keep diagnosis in the MIG torch or polarity path	move to control-state, feeder, and power-board logic
spool-gun-only failure	known-good base MIG setup first, then known-good spool gun	keep diagnosis in the spool gun or accessory branch	move back into the base machine only if plain MIG also fails
TIG-only start or current-control complaint	known-good `PRO17` torch and one control device only	keep diagnosis in the torch, pedal, or remote branch	move into TIG branch logic only after local TIG baseline still fails
all-lights flash or machine looks confused	strip back to base machine with no optional accessory connected and perform the documented `2T/4T` reset	keep diagnosis in state or control only if the fault remains stripped down	if the complaint disappears stripped down, keep it in the accessory path

Stop Rules

Stop if plain-steel base MIG is healthy. That means the machine is not generally dead.
Stop if the complaint follows only one remote, spool gun, or TIG kit.
Stop if the documented reset or stripped-down base-machine state clears the complaint.
Stop using the card and open the full guide if the stripped-down machine still shows the same control or power fault.
