ABSTRACT:
A soldering gun is provided including an elongated tubular body of quartz having first and second ends. The first end of the body is telescoped into an outwardly opening recess provided therefore in a soldering iron tip mounted from the first end and a second shorter and smaller diameter quartz tubular member is telescoped into the end of the larger diameter tubular member from which the tip is supported. A coil of 6 to 12 turns of Ni Chrome wire is disposed about the second quartz tubular member within the first quartz tubular member and the end of the coil adjacent the tip is reversely turned and directed back through the second quartz tubular member to a point adjacent the other end thereof. A two conductor extension cord is telescoped through a tubular handle and into the end of the larger diameter quartz tube remote from the tip and has one conductor thereof electrically conductor to the Ni Chrome wire end within the small diameter tubular member and the other conductor thereof electrically connected to the adjacent coil end of the wire outwardly of the small diameter tubular member, one end of the tubular handle being telescoped over and secured to the end of the large diameter tubular member remote from the tip.
