I work with about 300 tig weldors. NONE of us walk the cup. As a matter of fact, I had a student ( I am a tig instructor for nuclear, non-nuclear pipe, and structural tig quals) that came from another company, where he used to walk the cup all the time. I never told him NOT to walk the cup while he was qualifying here, he just decided to stop that technique and weld freehand.

There's a fine line between "hobby" and "mental illness".
