Sunstone Battery Welders

Sunstone Battery Welding systems allow you to weld highly conductive metals such as copper and aluminum, or traditional metals like nickel. They also come in a CNC version that is capable of performing all the same tasks with the assistance of a CNC table.


The motorized weld head adds excellent control, precision, and uniformity to every weld. Manufacturers can produce lighter, more compact battery packs without compromising power or capacity.


Features and Benefits

  • Solderless Connections – The metals are fused together at the weld spot for a continuous connection and no voltage drops.
  • Clean Weld Spots – During the welding process, surface contaminants are burned off, allowing for strong, clean welds.
  • Weld Dissimilar Metals – Sunstone Spot Welders can weld any combination of metals, such as Copper to Aluminum.
  • Small Heat Affected Zone – The heat affected zone (HAZ) is very small and very localized to ensure no degradation to the battery. The Orion provides enough energy to make the weld without affecting the integrity of the cell.
