F130 Measurement Card

This is the quick live-reading card for the highest-value F130 trigger-state, front-end, and generator-path splits.

Use This Card When

stable 120 V / 20 A source with any extension cord kept within the official 25 ft and full 20 A rating
correct front-end assembly
known-good clamp and current path
plain-steel 0.035 in flux-core baseline on a real 20 A source
proper 0.030 in conversion only with flipped drive roll and 11-30 tip if the machine is not on factory 0.035 in

Checkpoint	Where to measure or observe	Healthy expectation	If abnormal, keep diagnosis in...
Source and cord compliance	branch and extension-cord path at the machine	real `120 V / 20 A` baseline with no overlength or undersized cord	utility or extension-cord path
Trigger-state before trigger	control branch before trigger	roughly the documented low-state value	trigger or control branch
Trigger-state after trigger	control branch after trigger	rises to the documented working-state value	trigger or control branch
Feed behavior at idle	feeder with no trigger	stopped until command	trigger or control branch
Arc behavior with fresh front end	live weld on clean steel	stable enough to prove the machine	front-end, wire-quality, or clamp branch
OCV or live output baseline	arc-off or trigger-state baseline	about the official `46 V` class OCV and working-state rise into weldable range	output or control branch
Source behavior under weld load	branch at the machine	holds a true 120 V / 20 A class baseline	utility path

Use these only after the readings prove the complaint follows the torch front-end or accessory branch.

Stop if the source path still depends on an overlength or undersized extension cord.
Stop and keep the diagnosis in the trigger path if the before/after state split is wrong.
Stop if front-end correction or wire-quality correction removes the complaint.
Stop if left-hand-thread seat damage or front-end misassembly explains the no-arc branch.
Stop if the complaint disappears on the correct 0.035 in baseline or after a proper 0.030 in conversion with flipped drive roll and 11-30 tip.
Stop if the wire requires DCEP or is 0.023 in, because that is outside the intended F130 baseline.
Stop using the card and open the full guide if source quality and front-end proving are both clean but the machine still misbehaves.
