Lincoln Power Wave 455/STT Multi Process Welder

The Power Wave® 455M/STT® is built for high-performance industrial welding – especially robotic, hard automation and semiautomatic applications. It’s ideal when you need repeatable, high-quality welds in production environments such as automotive, structural steel, heavy fabrication and general manufacturing.

STT® (Surface Tension Transfer®) is a low heat-input welding process developed by Lincoln. On the Power Wave® 455M/STT®, it’s especially useful when you need:

• Tight heat control for thin materials or root passes

• Minimal distortion on sensitive components

• Reduced spatter, saving time on grinding and cleanup

• Lower fumes, improving the work environment

It’s a go-to process for demanding root runs, open butt joints and thin-gauge work where quality and control are critical.

The Power Wave® 455M/STT® is engineered specifically for robotic and hard automation:

• Digital control ensures repeatable welding programs

• Optional communication modules allow direct integration with robots and PLCs

• Multi-process capability means one platform can support various joints and materials

This makes it a strong foundation for high-throughput, highly automated welding cells.
