PulseWave200 Panel-State Drill

Drill Goal

• teach the trainee to separate panel-state faults from TIG hardware faults
• teach the correct order from measurement card to parts substitution to opening map

Starting Scenario

• Model: PulseWave200
• Complaint: the display shows all 8s after an arc event and TIG will not restart cleanly
• Arrival condition: a remote or pedal may be connected, and the torch polarity is unknown

Expected Document Sequence

1. PulseWave200 measurement card
2. PulseWave200 parts substitution card
3. PulseWave200 board opening map only if the stripped-down baseline still fails

Success Criteria

• the trainee says the first proof step is torch negative, base torch only, and sane gas flow
• the trainee uses the restore-default path before naming a hardware failure
• the trainee keeps remote-only complaints out of the internal branch until proven

Common Misses

• blaming HF hardware before proving torch polarity or gas setup
• ignoring the display reset path when all 8s are already present
• mixing AC-only and remote-only complaints into one false hardware story

Debrief

• The key lesson is that stored-state and accessory-path behavior are part of the diagnosis on this model, not cleanup after diagnosis.
• Internal opening is justified only after reset-state, torch path, and remote path are all bounded.
