Job Packet / WeldKing / ThunderCut65

Packet use

Use this packet when the complaint involves postflow with no start, delayed restrike, pilot that changes with pressure or RV1, or bad tracking with healthy power-up.
Primary guide: ThunderCut65 guide
Bench sheet: ThunderCut65 bench test

Intake snapshot

Item	Record
Serial or shop tag
Exact complaint
No start, weak pilot, or delayed restrike complaint
Air pressure under flow
Clamp placement on arrival
Torch-head mechanical condition
Guide or stand-off hardware in use

Likely parts and accessories to stage

Item	Why stage it early
Fresh A81 front-end stack	fastest way to remove torch-side false faults
Dry air source	pressure and dryness directly change restrike behavior
Known-good clamp and clean steel coupon	transfer complaints stay return-path heavy
Guide hardware only if the complaint involves tracking	separates guide faults from torch faults

Official parts-entry shortcuts

Use these after the diagnosis proves the fault follows the torch, guide, or air branch.

First branch decisions

If you see...	Stay in this branch first
Postflow normal but no start	torch-head mechanics branch
Pilot changes with pressure or RV1	air and pilot-maintain-current branch
Delayed restrike after warm-up	pressure, torch-head, and guide branch
Tracking complaint with healthy pilot	guide and stand-off hardware branch
Freehand cut is healthy but guided cut is not	guide, stand-off, or circle-kit hardware branch

Bench workflow

Normalize torch head, air pressure, and clamp.
Run ThunderCut65 bench test.
Prove a freehand baseline before trusting any guide-hardware complaint.
Keep pressure-sensitive and guide-hardware complaints separated, then warm retest for restrike delay.

Release signoff

Check	Result
Stable pilot restored	pass / fail
Stable transfer restored	pass / fail
Freehand baseline restored before guided cut	pass / fail
Short cut completed cleanly	pass / fail
Covers, grounds, and lead routing restored	pass / fail
