ABSTRACT:
An electric soldering iron has an elongated hollow handle casing having a tubular hollow holder extending from one end thereof and supporting a soldering bit heated by an electric heater within the holder. A forked suction pipe is secured to the holder and includes a main pipe having an intake port at one end disposed adjacent to the soldering tip and an outlet port at its other end connected to an induced-draft fan assembly through a flexible air pipe. A branch pipe of the suction pipe extends laterally from the main pipe and has an intake port connecterd to the interior of the casing through a heat resistant hose. Actuation of the induced-draft fan causes soldering fumes generated at the tip to be drawn into the main pipe and for cooling ambient air to be drawn through the casing from an inlet at its other end to remove excess heat from the casing.
