The MARC 3 is an automated nut welding machine engineered for pad welding using rotating arc technology. Designed for high-strength, gas-tight connections, this system is suitable for welding nuts and hollow cylindrical components across a wide range of industrial applications.
Its programmable controls, inverter-based power source, and linear motor-driven welding head provide precise process management while minimizing heat input and material distortion.
The MARC 3 was developed to provide a highly controlled nut welding process for manufacturers requiring strong, leak-tight welded connections. Its rotating arc technology creates uniform weld formation while maintaining low thermal impact on the surrounding material.
The system utilizes a rotating arc welding method specifically designed for pad welding applications. This process creates a continuous welded connection around the entire component, producing excellent mechanical strength and sealing performance.
With the ability to weld components ranging from M4 to M18, the MARC 3 supports a wide variety of manufacturing applications. The system accommodates both external diameters and internally threaded components, providing flexibility across multiple production environments.
Operators can independently program welding current, welding time, motion profiles, welding piston functions, and shielding gas parameters. This flexibility allows manufacturers to optimize the process for different materials and production requirements.
The integrated linear motor welding head provides precise movement and repeatable positioning throughout the welding cycle. This contributes to consistent weld quality and improved process stability.
One of the key advantages of the MARC 3 is its ability to produce strong welds while introducing minimal heat into the workpiece. Reduced thermal impact helps limit distortion and preserves dimensional accuracy on finished components.
The rotating arc process produces closed, pressure-sealed welds that are well-suited for applications requiring gas-tight performance. The system can be used for manifolds and other assemblies where sealing integrity is critical.
Every production environment has different requirements. We can help you evaluate whether the MARC 3 provides the performance and welding capabilities your operation requires.
