ABSTRACT:
A portable, handheld seam welding gun for filling in seams between sheets of linoleum flooring is provided with a unique heat nozzle. The heat nozzle of the invention couples the heating barrel of a conventional floor seam welding gun to a conventional hollow welding tip by receiving the heating air inlet tube of the tip within the confines of a downstream socket formed in the body of the heat nozzle. A larger, upstream socket formed in the body of the heat nozzle fits onto the heating barrel of the handheld, portable welding gun. A plurality of preheating jets are formed on the underside of the body of the heat nozzle to preheat the region of the channel immediately to the rear of the welding tip just before molten sealant flows into that portion of the channel.
