An articulated welding boom is disclosed, the boom having two guide modules above and below the primary swivel joint. The swivel joint itself is insulated from wire used to weld to prevent unwanted arcing. A wire feeder is mounted at an end of the secondary arm. Flexible wire conduit connects the guide module and the wire feeder, and the secondary arm folds down so that the operator can load or unjam the feeder without a ladder or lift.

Examples of the present disclosure relate to a tape attaching apparatus of which an installation space is reduced, with productivity of tape attaching work improved, and accuracy of a tape attachment position is improved. Examples of the present disclosure include a tape attaching apparatus including a tape supply unit that supplies a tape, an electrode plate supply unit that supplies an electrode plate, and a rotating head that receives the tape supplied from the tape supply unit and rotates to attach the tape to the electrode plate supplied from the electrode plate supply unit.
