A220 Parts Substitution Card

This is the quick external-parts substitution card for the highest-value A220 clamp, holder, and utility-path splits.

Use This Card When

top-end arc feels weak
rod behavior is poor even though the machine powers normally
clamp, holder, or plug heating may still be the real problem
the complaint changed after lead service, plug work, or source change

Stage First

known-good heavy-duty clamp
known-good holder branch
dry 7018 or 6010/6011 class rod
stable 230 V class source, ideally 50 A for top-end proof, or healthy 5 kW generator path

Fast Substitution Card

Complaint branch	Swap first	If the complaint follows the part...	If the complaint stays with the machine...
poor rod behavior with normal power-up	known-good clamp and holder	keep diagnosis in the current path	move to utility or output logic
weak top-end performance	stable utility source and known-good current path	keep diagnosis in utility or current path	move deeper only if the healthy source still fails
complaint starts after lead service or setup change	correct DCEN / DCEP lead placement for the actual rod test	keep diagnosis in setup and external current path	move deeper only if the arc is still wrong with correct polarity
hot clamp, holder, or plug	known-good heavy-duty current path	keep diagnosis external and mechanical	move to machine output only after heating path is proven
no useful output with healthy externals	hold known-good current path steady	keep diagnosis external if the complaint follows the leads	move to output branch only after external proof

Stop Rules

Stop if clamp or holder substitution fixes the complaint.
Stop if a stronger source removes the failure.
Stop if correct polarity and known-good high-load proof rod remove the complaint.
Stop if the machine is being evaluated as TIG, because A220 is officially not recommended for TIG welding.
Stop using the card and open the full guide if current path, utility path, and output behavior are already proven clean.
