ABSTRACT:
An apparatus is provided for sealing seams between adjacent sheets of flooring which define an upwardly facing, elongated groove where they meet. A conventional hand-held portable seam welding gun has a body defining a longitudinal axis. A heat concentration nose is mounted on a heat conducting member. A heating tip mounting post projects at an angle of at least about fifteen degrees, from the longitudinal axis of the seam welding gun. A hollow heating tip employed on the mounting post is provided with a forwardly directed, upturned toe having a concave, downwardly facing groove therein forward of the front extremity of a sealant dispensing mouth. Also, a heating duct extends between the melting chamber of the heating tip and an orifice located behind the rear extremity of the sealant dispensing mouth. The welding gun employs a mobile, stabilizing guide formed with a pair of laterally spaced outboard rollers and a seam follower located midway between the rollers and a track follower that rides in the groove between adjacent flooring sheets. An adapter secures the guide to the welding gun body. A releasable fastener between the guide and the adapter holds the welding gun at a desired angle to the floor.
