1. Can be freely combined based on the weight and length of welding pieces, offering convenience and flexibility in use.

2. Automatically adjusts the roller center distance within specified limits, suitable for different diameters of welding parts; the cylindrical welding parts are placed evenly.

3. Silicon-controlled rectifier (SCR) powered DC motor drive, variable speed control, wide welding speed range, stable speed.

4. Versatile and widely applicable

5. Composite roller design with rubber-coated steel wheel, offering smooth transmission, high friction, and extended lifespan.

6. A smaller workpiece wheel pressure can prevent cold working hardening of the working surface.
