Frequently asked questions
Is it compatible with my 936 soldering iron?
The listing says it is compatible with 936-series temperature-controlled irons. Confirm your iron's model and the 4-wire layout, since the element must match the handle and control board.
Why does the element have four wires?
Two wires feed the heater and two connect the temperature sensor, so the controller can read the element temperature. When testing, compare the measured resistances with the listed room-temperature values.
