Product Questions
Typical catalog applications include layered copper foil, copper braid, strip and other conductive assemblies. The exact stack must be reviewed.
Selection considers weld area, layer stack, pressure, heating requirement, tooling size and target cycle.
Tooling geometry and effective weld area can be evaluated against the workpiece drawing and layer stack.
Provide material grades, layer thicknesses, finished connection dimensions, insulation constraints, target output and photos or drawings.
DR Series
Capacitor Discharge Spot Welders
The DR series stores electrical energy in capacitors and releases it through the welding transformer for short-duration resistance spot and projection welding.
