Manual way to purge PP205si and torch lines ?

Is there any button or switch combination that will cause PP205si internal gas flow solenoid to Open without activating TIG or Stick Welding or Plasma cutting power?


Looking for an easy way to ensure PP205si and lines are purged of Argon when switching to Plasma cutting or lines are purged of Compressed air when switching to TIG welding. Along with being able to bleed pressure off PP205si and lines when done.

Going to use a "Y" valve at gas input of PP205si to select between Compressed air or Argon gas, to keep from having to undo hose connections to swap between TIG and Plasma.

Thanks!

Turn up the post flow. Tap the pedal or switch.

I'll give it a try. I thought about doing that. But was worried that pulling trigger on TIG or Plasma Torch with them being in use could damage HF Arc start for either.
Figured it was better to ask if there was an undocumented way to cause a Air or Argon gas purge.

Thanks for reply.

Just don't hold the trigger or pedal down. Just tap it.
