Abstract
A torch for cutting, gouging or welding metal including a body having a central longitudinal axis for connection to sources of pressurized gas and electrical potential and a swivel housing threadably connected to the body for rotation relative to the body about the axis and a tubular handle around the body and the swivel housing. The handle has front and rear sections manually relatively rotatable. The front section and swivel housing are rotatable as a unit, and the rear section and body are rotatable as a unit so that rotation of one section relative to the other effects rotation of the swivel housing relative to the body. The torch includes a head forward of the swivel housing having an opening for holding an electrode and includes an elongate unitary swivel member having a forward end non-rotatably attached to the head and a rearward swivel end disposed in an opening of the swivel housing. The swivel end of the swivel member is rotatable on the axis and swivelable in the housing opening to position the head in a selected angular position. The torch includes a locking system responsive to manual rotation of the front and rear handle sections relative to one another to releasably hold the swivel end of the swivel member fixed in the housing opening to lock the head in the selected position and an enlarged gripping formation on the front handle section.
