<p>PURPOSE:To properly fix the molten resin of the bonding part of a resin product to be melted and welded by providing a controller controlling the heat value of a heating element on the basis of a heat pattern stopping melt-welding work. CONSTITUTION:A display device 9, the sound synthesizing circuit 42 of a speaker 10, a potentiometer 28, a temp. sensor 34 and a memory 43 storing a heat pattern are connected to a controller 40. The heating element 21 of a joint 17 is connected to the controller 40 through a connector 15 and the kind of the joint 17 is discriminated on the basis of the output of the potentiometer 28. The heat pattern corresponding to the kind of the joint 17 is selected and set and the heat value of the heating element 21 is controlled on the basis of the heat pattern.</p> |
