Thermocouple Welding

Thermocouple Welding

Pulse-Arc (Micro TIG) Welding Thermocouples

One of the most common sensors in the world is Thermocouples. They are used in almost every consumer product in the world. In the manufacturing, construction, or internals of every product, we use on a daily basis. Sunstone aims to make thermocouple welding easy. No need for guessing if you have a good connection or contact with your piece. Let Sunstone help you simplify your thermocouples.

The Precision You Need

Sunstone Welders specializes in micro welding and explicitly designs for high levels of precision. When you are working with delicate wires, thin sheets, or precise sensors, Sunstone can give you the accuracy and precision that you need.

The Power You Need

Sunstone Welders provide units with the power to accomplish a wide range of welding applications. From fine wire welding, Stranded and Solid Wire applications. No matter the weld you need, Sunstone Has a Solution for you.

Sunstone offers a variety of thermocouple welders. The Orion Pulse Arc Welders works well for creating consistent, uniform bead junctions by utilizing pulse arc (or micro TIG) technology to weld thermocouple junctions. Sunstone offers Capacitive Discharge Welders that can also be used to weld thermocouple junctions. These systems will weld thermocouples directly to the metal piece for temperature sensing.

Sunstone's Orion welders are capable of welding the largest variety of materials and sizes of thermocouple junctions. The added benefit comes from Orion’s versatility and the ability it has to weld even highly conductive metals.
