Versatile machines for a wide range of resistance welding applications.

Weld Systems Integrators PRESS-TYPE Projection and Spot welders are manufactured to be durable, heavy-duty machines. Each machine is air operated and water-cooled for many years of reliable service.

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 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.
