Delivering long-lasting welding with a user-friendly, heavy duty and flexible track-mounted welding carriage perfectly integrated with any Böhler Welding MIG-MAG welding equipment.

railRunner is able to show its strengths in any welding position. Thanks to the programmable oscillator and the unique user interface you have all controls in your hand. The perfect alignment of Böhler Welding Equipment and consumables brings productivity to the next level with the all new railRunner.

Your benefits:

  • High voltage remoted - safety on the job site without the need for batteries with 36 V DC only at the work site 
  • Single user interface - welding process and movements in one hand because of wire speed, arc length, voltage and movement control
  • Perfect alignment with Böhler Welding consumables and equipment - excellent welding performances due to compatibility with all TERRA & URANOS equipment

See for yourself

  • User-friendly - easy and fast set-up
  • Perfect for heavy-duty welding operations - rugged & tireless
  • Flexible - versatile for on-site and in-shop welding
  • Max. duty cycle
  • Higher productivity and quality with optimized performances
  • Multipurpose - for any type of heavy-duty welding operations

Any kind of heavy-duty welds, whether fillet, butt or lap weld, can be profitably welded using this solution both on-site and in-shop. Any position is possible including frontal vertical and overhead, on straight and curved surfaces. Applications might be found in multiple industry segments, from beams, frames to tanks and other massive industrial components. The perfect weld seam is achieved thanks to specific Böhler Arc welding programs and productivity further improved with the Böhler Welding special processes such as rapiDeep and QuickPulse.
