Abstract
Abstract A welding machine for simultaneously welding a plurality of studs on a beam (particularly an I-beam) comprising a frame with front and rear wheels for engaging the beam. A plurality of welding heads are mounted on a supporting means and each head includes a chuck for holding a stud; means for moving the chuck away from the beam; means for moving the chuck toward the beam; and, means for supplying electric power to the chuck. The heads are mounted for vertical and horizontal adjustment relative to the frame. Guide means are provided between the machine and the beam to properly orient the machine relative thereto and means are provided for raising and lowering said heads and supporting means as a unit relative to the wheels of the machine.
