ABSTRACT:
A device for welding roof membranes which includes a heat welding means capable of applying a heat weld to overlapping roof membranes, and a fluid application means capable of applying a solvent or primer between overlapping roof membranes in order to form a solvent weld to the roof membranes or to aid in preparing the membranes for application of a heat weld to the membranes. The device may be employed to apply, for example, a heat weld to overlapping roof membranes on one side of a fastening means, and a solvent weld to the overlapping roof membranes on the opposite side of the fastening means. Such a device enables one to apply solvent or primer safely while providing the ability to apply, if desired, a heat weld in addition to the application solvent or primer.
