The Advantages of Capacitive Discharge Spot Welders

Capacitive discharge spot welders (CD spot welders) have many advantages over other welding technologies:

  • Quick energy release for welding highly conductive metals such as copper
  • Small heat-affected weld zones
  • Repeatable energy release independent of line voltage fluctuations
  • Capable of extremely fine energy adjustment


Capacitive Discharge spot welders are one of the most cost-effective welding solutions for fine-spot resistance welding. Whether you are manufacturing battery packs of microscopic assemblies, Sunstone Capacitive Discharge spot welders are the most affordable, precision fine-spot resistance welders on the market.

AC Welders

AC Resistance Seam Welders are used to complete AC Resistance welds. These would include both spot welds and seam welds. Ideal for creating a continuous seam weld, foil welding, Pouch cell welding, and mesh or screen welding. The primary applications include the creation of hermetic seal with a pouch or package. Additionally, AC Resistance seam welders create and build filter assemblies, filter bodies, and attaching mesh screen to a strainer basket. Additional applications include filter baskets, battery cells, and any metal filter or screen.

DC Welders

The Sunstone Linear DC welder is a completely unique resistance welding system with closed-loop feedback. Utilizing new patent pending technologies, the Linear DC welder has the power of a High-Frequency Inverter and the precision of a Linear DC. As mentioned, this is a completely unique product. It isn’t an HF welder since it does not require an external transformer, and it isn’t like typical Linear DC welders because it doesn’t use transistors to control the energy output. Yet, this product is able to perform the same functions as both of these technologies, and in most cases it has capabilities that exceed those of other HF or Linear DC welders – offering high repetition rates, fine low-energy control, and short or long weld times – without any of the drawbacks and inconveniences.
