MAG211 Measurement Card

This is the quick live-reading card for the highest-value MAG211 chart, gas-solenoid, and spool-gun branch splits.

Use This Card When

the arc is rough or chart-sensitive
gas command is dead or erratic
the complaint follows only the spool-gun branch

Prove First

correct base-gun setup with plain-steel wire
chart-correct baseline before chasing instability
known-good gun path before spool-gun proving

Fast Measurement Card

Checkpoint	Where to measure or observe	Healthy expectation	If abnormal, keep diagnosis in...
Gas-solenoid branch on trigger	gas-valve branch during trigger	roughly the documented MAG-family level, not dead or erratic	gas-valve or control branch
Bare-wire feed response	wire feed with tip removed	smooth feed on command	drive path or control branch
Arc smoothness on short weld	live weld behavior	stable plain-steel arc with no obvious ripple-heavy buzz	ripple or internal power branch
Base gun versus spool gun	compare base gun to spool gun	base gun proves first, spool-gun complaint stays isolated	spool-gun and drive-roll branch

Official Parts Shortcuts

Use these only after the readings prove the complaint follows the external gun, spool-gun, or drive-roll branch.

Stop Rules

Stop and correct chart or front-end setup first if the arc smooths out immediately.
Stop and keep the diagnosis external if the base gun is healthy and only the spool gun fails.
Stop using the card and open the full guide if gas, feed, and output branches do not align to one clear path.
