Abstract
An electric soldering iron includes a barrel and a head portion with a center hole being pivoted to a front end of the barrel. A piston and a piston rod are disposed in the front end of the barrel. A spring embraces the piston rod and bears against the piston. A solenoid is disposed in a rear end of the barrel. A button is disposed at a rear end of the barrel for controlling the solenoid. The piston is pushed forward by the spring when the solenoid is not actuated. A depression of the button actuates the solenoid to draw the piston rearward.
