How to Make A Thermocouple

Thermocouple Assembly

1. Obtain a k-type thermocouple wire.
2. Separate the two ends such that the ends are not touching.
3. Twist the two ends together such that the ends are barely being held together by the twist.
4. Turn on the electrode instrument which will be used to weld the two wire ends together at the twist.
5. Ensuring that you are NOT touching the metal wire place the twist on the electrode and push the button which uses an electric current to weld the wire ends at the twist.
6. Weld the wires together so that there is a metal ball on the end which is about 1mm in diameter.
7. Untwist the wires if part of the initial twist still is present to avoid short circuiting the thermocouple.
