How did "clean" even get into the discussion?
"Clearing the path" and "cleaning" are two completely different functions.
"Clearing the path" is a slang term that refers to the inert gas being shot ahead of the intended weld area, pushing any airborne contaminants out of the way, when a pushing motion is used.
"Cleaning" is a mechanical process.
Somehow you guys got the two words mixed up.
