Abstract
A positionable welding torch for a welding system is featured. The torch comprises a torch head, a handle, and a flexible portion coupled to the torch head and the handle. The flexible portion is adapted to enable the torch head to be positioned relative to the handle. The flexible portion has a first end, a second end, and a rigid restraining member adapted to cooperate with the first and second ends to limit the relative displacement of the first and second ends. The restraining member may comprise a restraining portion adapted to abut one of the first and second end portions. The restraining member also may comprise a biasing portion adapted to bias the restraining portion into engagement with one of the first and second end portions. A method for assembling a welding torch having a restraining member also is featured.
