摘要

A device for welding overlapping roof membranes comprising a chassis, an air discharge chute and a flame distribution assembly communicating with the air discharge chute. The flame distribution assembly includes a gaseous fuel source inlet, a primary burner, and an ignition source. A control unit ignites the primary burner by the ignition source. The blower connected to an inlet port of the air discharge chute directs heat generated by the primary burner through an air discharge outlet for welding the overlapping roof membranes.
