Patent ID: 7886954

Claim:
A solder handling temperature controller designed to control a solder handling device including a soldering iron to have a given set temperature, under a condition that it is in connected relation with the solder handling device or incorporated in the solder handling device, the solder handling temperature controller comprising: a body of the solder handling temperature controller; a rotating shaft housed in the body and adapted to be rotatable about an axis thereof; a set temperature changing device adapted to change the set temperature according to a rotation angle of the rotating shaft; a rotary knob supported by the body in coaxial relation with the rotating shaft and in a rotatable manner relative to the rotating shaft; and a temperature lock key adapted to be selectively inserted into and withdrawable from the body in a position coaxial with the rotating shaft and the knob, and, in an inserted state thereof, to mechanically couple the rotating shaft and the knob together to allow them to be interlockingly rotated, wherein, in a state where the temperature lock key is withdrawn from the body, the coupling between the rotating shaft and the knob is released to prohibit a change of the set temperature by rotation of the knob.
