ABSTRACT:
The invention relates to a handheld welding tool with external air supply for welding thermoplastic synthetic material, with a preferably wand-shaped housing containing at least one hot air generating device, and with flexible supply lines for air and power supply that are combined in a supply line package. The supply lines of the supply line package are connected with rear connection elements on the housing, to the supply line for the air supply encasing the power supply line as a sheath. The invention proposes to connect the supply line package rotatably to a common rear non-rotatable connection piece of the housing. This makes it possible to rotate the handheld welding tool with little force in relation to the supply line package in order to facilitate the handling of the handheld welding tool.
