MigSonic145 Measurement Card

This is the quick live-reading card for the highest-value MigSonic145 support-power, feed-control, and gas-side splits.

Use This Card When

the machine clicks on and off
the feeder runs wrong or loses control
the weld goes bad only in gas-shielded setup

Prove First

correct wire path with tip removed if feed is in question
known-good NT-1 gun branch
known-good regulator and hose only if the complaint is gas related

Fast Measurement Card

Wire-speed response	wire-speed control during trigger	tracks control change cleanly	control branch
Gas-shielded weld behavior	live weld with known-good gas path	normal coverage and stable arc	regulator, hose, or gas-side branch

Stop Rules

Stop and correct source or support-power issues first if the machine click-cycles.
Stop if a known-good regulator or hose removes the complaint.
Stop using the card and open the full guide if the machine and gas branches both look healthy but output still collapses.
