Abstract
Welding devices and methods of using the same are provided. The welding device includes a rotor assembly. The rotor assembly includes a first semi-collar associated with a second semi-collar to form a collar. The collar is adapted to be disposed about a tube to be welded, and associated with an automatic voltage control assembly. The automatic voltage control assembly is mechanically associated with an electrode, and the automatic voltage control maintains the desired angular disposition of the electrode relative to the tube to be welded.
