<p>The present invention provides an electric soldering iron having a temperature setting device comprising: a handle wherein a circuit board and a sensor are mounted which enables users to grasp it to carry out soldering; a power plug on one end of the handle to electrically be connected to an outlet or a power strip, and to be connected to an electric wire to supply an alternating current power source; and a tip on the other end of the handle to be heated to a certain temperature using the alternating current power source to weld lead using the heat. The handle is made of a transparent synthetic resin. A temperature rise button and a temperature drop button protrude from the bottom of the handle to enable users to set the temperature. An LCD window to display a precise temperature set by the press of the temperature rise and drop buttons into Arabic numbers is arranged inside the handle. Therefore, the electric soldering iron having a temperature setting device enables users to precisely set the temperature.</p> |
