The spot welded wires are more accurate than the beads. Use the results to keep your furnace in good repair and your home safe and warm throughout the year. When one end of the thermocouple reaches a higher temperature, electrons flow through the wire toward the other end, and fewer electrons are left behind on the hot side. A better option for many is the use of temperature transmitters or signal conditioners. Be careful not to overexpose the scene by pointing the flashlight directly at the camera. TIG welding: I tried to weld a both TC and bare TC wire to an aluminum plate by forming a small puddle on the plate and then attempting to dip the wire into the puddle while quickly extinguishing the arc. MathJax reference. Remember that the only temperature a thermocouple measures is its own temperature. Cross them at right angles. A good pilot light flame is blue. Well, it requires a deep understanding of its inner workings and a mastery of its intricacies.
