Product Questions
It is considered when a short energy pulse and reduced heat duration are useful for the joint. Suitability still depends on the material, geometry and contact condition.
The catalog lists plated components among typical applications, but the actual coating and surface requirement should be tested.
Stored energy, required current, joint area, electrode force and acceptable marking are reviewed together.
Electrodes and fixtures can be scoped after drawings, photos or samples are reviewed.
DBZ Series
MFDC Spot & Projection Welders
The DBZ series is an MFDC pneumatic resistance welding platform for spot and projection welding. Model selection depends on material, stack thickness, electrode access, required force, cycle rate and available three-phase power.
