ABSTRACT:
In a soldering system which utilizes a fine jet of very hot gas for heating the work point the hot air may impinge directly on the work point or it may heat a soldering tip from within whereby it may be used in a more conventional mode of soldering or desoldering. A regulated flow of gas to the heater of the soldering instrument may be somewhat preheated by passing along the leads carrying the electric power to the heating element. The same supply of air may also be used to cool the handle of the handle of the soldering instrument for operator comfort and safety. The temperature of the heating element is remotely electronically controlled by a time share use of the power leads as temperature sensing and feedback.
