A solder gun or soldering iron contains a pair of electrical terminals that hold a solder tip containing a pair of straight parallel leads. Each lead has a substantially U-shaped cross-section that creates a circular cavity filled which is filled with an insulative material. The soldering tip is made from either a low impedance material such as copper or high impedance material such as a multi-layer material of steel, copper and nickel that automatically maintains the soldering tip at a constant temperature. The soldering device also comprises a universal connector that receives both a solid solder tip and a hollow soldering tip. A rack extending around the soldering device allows quick and easy exchange of various solder tips into the universal connector. In another embodiment of the invention, the soldering device includes a multiple position trigger that both initiates heating of a solder tip and activates a suction mechanism.
