WeldKing Certification Checkoff

This checkoff decides whether a trainee is ready to use the WeldKing workflow on supervised live customer units. It does not authorize independent repair work. The trainer should use it only after the trainee finishes the WeldKing progression and demonstrates stable document-order discipline.

Scope

Brand family covered: WeldKing training built around CoolArc160, CoolArc200, PulseWave200, and MultiSonic220
Authorization level after pass: supervised live-unit work only
Minimum expectation: the trainee can follow the WeldKing document stack without prompting and can stop before unjustified internal repair

Required Evidence Before Checkoff

all drills in the WeldKing training drill pack completed
all answer keys in the WeldKing training assessment pack reviewed
a completed WeldKing score sheet from the training assessment pack
trainer observation of at least one tabletop run and one bench-style run
completion of the WeldKing training progression

Checkoff Areas

Area	Trainee must demonstrate	Evidence source	Pass standard
Complaint classification	names the complaint family correctly before opening diagrams	drill response and instructor observation	correct on all staged complaints
First proof step	states the first external proof step before touching internal references	drills, answer keys, and live questioning	no skipped first-proof step during the checkoff
Document order	moves through router, measurement card, substitution path, and full guide in the right order	observed drill flow	no random document hopping and no skipped stop rule
Measurement discipline	takes the expected reading in the correct state and explains what it means	bench simulation and answer-key review	readings are taken in the right place and interpreted correctly
State and setup discipline	resets or strips to local control when the complaint family requires it	PulseWave200 and MultiSonic220 drills	no panel-state or process-state confusion left unresolved
Substitution discipline	proves the easiest external assembly before proposing internal repair	CoolArc160, PulseWave200, and MultiSonic220 drills	no premature board suspicion while external proof remains available
Internal escalation discipline	identifies the exact stop point where internal access becomes justified	all drills and trainer questioning	escalation threshold is stated clearly and consistently
Communication and closeout	explains the branch taken, evidence gathered, and next action clearly	trainer interview and score sheet	explanation is concise, ordered, and technically coherent

Automatic Rework Triggers

opening the machine before proving branch power, OCV, input-sense behavior, or external hardware condition
treating expected low-line or wrong-input behavior as a defective machine
confusing digital state with hardware failure after the reset-first step was available
failing to isolate process, polarity, or feeder path on the MultiSonic220 scenario
relying on a guessed connector or board identity instead of the local reference set

Signoff Decision

Ready for supervised live-unit work: trainee passes all checkoff areas with no automatic rework trigger.
Ready after one targeted re-run: trainee is close, but one area such as measurement discipline or document order still needs a controlled repeat.
Not ready: trainee triggers one or more automatic rework conditions or cannot explain the escalation boundary clearly.

Suggested First Live-Work Envelope After Pass

low-risk intake triage with a trainer present
external-path proof and document routing on known complaint families
no unsupervised internal teardown
no final customer release decision without trainer review
