Overview and Applications

Sunstone Spot Welders built with Sunstone Technology have key advantages and capabilities when welding exotic metals and alloys. Due to the metal properties and compositions, some metals are more difficult to weld than others. Sunstone’s technology and expertise with welding exotic metals can help with finding an appropriate and affordable welding solution.

Commonly welded exotic metals include Titanium, Inconel, Cobalt, Stainless Steel, Steel Alloys, Magnesium, Aluminum, and more. See our comprehensive listing of exotic metals below. If your particular metal is not listed, please contact us to discuss with us your application.

EV Copper Tab Battery Welder

250i² EV

The Orion 250i² welding system is the most impressive pulse Arc welding system. With the ability to weld aluminum and copper and large thick pieces.

Orion 200i² Welding System

The Orion 200i² welding system is the most advanced Pulse Arc welding system. With the ability to weld extremely small wires, up to large thick molds the Orion 200i² can weld the broadest range of applications.

Linear DC Power Supply

Sunstone’s most advanced Resistance welding system. With the power of an HF Inverter, but the Control and low-end welding capabilities of a Linear DC. The Linear DC includes advanced features that allow for current monitoring, Touch Screen Controls, Saved settings, and handpiece and foot pedal activation.

Tweezer Hand Attachments

Tweezer Hand Attachments are designed for situations when weld force is required to pinch two parts together and an opposed weld head is not feasible due to part geometry or weld locations. Pneumatic or manual actuation allows for quick, repeatable, high force welds that provide consistent quality.

Hand Held Attachments

Hand attachments coupled with a Sunstone welder can provide amazing solutions for your application. Pressure is equally important as energy in resistance welding. The use of a pressure actuated hand attachment allows for consistent pressure with each weld. This will provide optimal welding results, with the freedom of a handpiece.

Weld Heads

We offer a variety of weld heads such as opposed and parallel. They come in various actuation methods including pneumatic or manual cable driven. Our weld heads offer consistent pressure at the weld site and provide easy weld activation for increased productivity.
