IDW-1800T MFDC Resistance Welding Power Supply for Metal Fabrication & Industrial Manufacturing
The IDW-1800T MFDC resistance welding power supply is designed for demanding industrial welding applications requiring high output current, precise process control and consistent welding quality. Combining advanced medium frequency inverter technology with intelligent welding management, IDW-1800T provides a reliable solution for metal fabrication, steel structures, wire products, metal furniture and industrial hardware manufacturing.
With a maximum output current of 1800A and rated power of 350KVA, the IDW-1800T delivers powerful performance for high-current resistance welding applications. Operating at selectable frequencies of 1kHz or 4kHz, the system supports two control modes: constant peak current and constant conduction angle. These flexible control options allow manufacturers to optimize welding parameters according to different materials, workpiece thicknesses and production requirements.
The IDW-1800T supports three-stage welding processes, including preheating, main welding and tempering. Operators can independently configure welding steps, current reduction and recycling times to achieve suitable welding conditions for different workpieces. Real-time secondary current measurement through a toroidal coil provides feedback to the controller, helping maintain accurate welding current and improve process stability.
Compared with traditional AC resistance welding systems, MFDC technology converts input power into medium-frequency direct current, providing concentrated welding energy and fast current response. The low-voltage, high-current welding configuration helps improve energy utilization, reduce unnecessary heat generation and achieve consistent welding results, particularly when joining multilayer metal sheets, thick steel plates and conductive metal components.
The IDW-1800T is suitable for a wide range of industrial resistance spot welding applications, including steel furniture, supermarket shelving, wire mesh, metal cabinets, electrical enclosures, metal brackets, hardware products, steel structures and construction components. The system can also support customized welding applications involving copper, stainless steel and carbon steel, depending on workpiece specifications and welding requirements.
