The Denka PR-1000 is a high-power projection resistance welding machine, often featuring Miyachi Weldtech controls for industrial applications, boasting up to 200kVA and 735daN force. These machines typically feature water-cooled transformers, pneumatic cylinder heads, and advanced controllers for heavy-duty welding, suitable for nut and stud projection.Key Features & Typical SpecsModel: Denka PR-1000 Projection Welder.Max Power: Up to 200kVA.Max Force: ~735 daN.Control Unit: Typically equipped with Miyachi Weltouch CY-2108.Operation: Pneumatic straight-action design.For similar industrial projection welding, linear spot welders such as the weldmax vlp35 offer robust 35kVA performance.Typical ComponentsWater Cooling: Used for the transformer, plates, and electrode holders.Pneumatic System: Double-stroke cylinder with lubrication-free components.Safety: Two-hand safety control, essential for projection welding setups.These machines are specialized for projection welding, which differs from spot welding by allowing the welding of multiple points or fasteners simultaneously.
