ABSTRACT:
Methods of arc welding and an arc welding assembly comprise a power source configured to provide a welding current, and a single weld housing. The weld housing comprises a welding torch, which comprises a consumable electrode wire. The welding torch defining an elongated member configured to utilize the welding current to melt at least part of the consumable electrode wire and provide welding current to the work piece. The weld housing further comprises a bypass torch defining an elongated member configured to divert a portion of the welding current away from the work piece while allowing other portions of the current to flow to the work piece.
