Job Packet / WeldKing / TIG200PACDC

Packet use

Use this packet when the complaint involves DC good but AC bad, pedal-only faults, erratic gas behavior, or TIG dead while stick still works.
Primary guide: TIG200PACDC guide
Bench sheet: TIG200PACDC bench test
Brand references: WeldKing local reference manifest, WeldKing fault-branch matrix

Intake snapshot

Item	Record
Serial or shop tag
Exact complaint
DC TIG, AC TIG, or both affected
Pedal or remote path in use
Gas setup and flow state
Stick branch behavior if tested

Likely parts and accessories to stage

Item	Why stage it early
Known-good TIG torch and tungsten	removes common torch-side false faults
Known-good gas regulator and hose path	shielding complaints still dominate these machines
Known-good pedal only if the complaint involves it	avoids mixing remote faults into the base-machine test
Meter for mode and response checks	needed when the complaint is AC/DC-state specific

Official parts-entry shortcuts

Use these after the diagnosis proves the fault follows the gas or remote-accessory branch.

First branch decisions

If you see...	Stay in this branch first
DC TIG healthy but AC TIG unstable	AC-mode branch
Complaint follows one pedal only	remote or pedal branch
Gas-flow complaint changes immediately with setup correction	gas branch
Stick healthy while TIG stays dead	TIG-only branch

Bench workflow

Normalize gas path, confirm the pedal branch if used is the correct 4K7 family, and simplify to DC TIG.
Run TIG200PACDC bench test.
Prove AC TIG only after DC is healthy.
Add pedal proving only if the base machine is already stable.

Release signoff

Check	Result
DC TIG baseline restored	pass / fail
AC TIG baseline restored if required	pass / fail
Correct pedal or remote response proved if required	pass / fail
Pedal or remote branch proven healthy if required	pass / fail
Covers, grounds, and lead routing restored	pass / fail
