01 / 02MFDC spot and projection welding / 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.
- DC welding output from a medium-frequency inverter platform
- Closed-loop voltage and current monitoring
- Adjustable current rise profile
- Touch interface with weld counting and data storage
Final configuration is reviewed against your workpiece, joint and production target.

Product Overview
Process definition
Medium-frequency direct-current resistance welding converts three-phase input power into a controlled DC welding output for repeatable spot and projection joints.
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.

Product Questions
Share the material, stack thickness, joint drawing, weld count, electrode access, target cycle time, available power and destination country.
Selection is based on the required welding current, force, workpiece access and validation target rather than rated capacity alone.
Application-specific electrodes and fixtures can be evaluated after the workpiece drawing or sample is reviewed.
The catalog reference is three-phase 380 V power, 0.6 MPa compressed air and 24 L/min cooling water. Destination requirements must be confirmed.
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.
