Spot Welding, Projection Welding and Combined Spot / Projection Welding

Press type welders from Weld Systems Integrators can be configured for spot welding, projection welding and combined spot / projection welding applications. Furthermore, our durable, heavy-duty press-type welders are air-operated and water-cooled, manufactured for many years of consistent, reliable service.

Press Type Welders – Versatile machines for a wide range of resistance welding applications.

In the engineering stages, WSI utilizes the latest in computer-aided design software. The manufacturing process delivers precision machining for all frame requirements. Assembly utilizes state of the art components with time tested manufacturing techniques for a high performance, value-driven welder. The welders are tested under full power, certifying compliance to rigid specifications.

Each press type welder is manufactured for a lifetime of performance.

WSI welders are an excellent choice for stand-alone tasks. They can be coupled with value-added feeding equipment or tooling with parts eject system for ease and speed of operator use. Projection and spot welding machines can also be integrated into a manufacturing system, part of a work task cell, integrated into a robot cell, or designed into multi-spot requirement applications. Please feel free to contact our application engineers for your specific needs.
