Meet the Steelmax Beam Runner CDL, the cordless, dual-torch welding tractor built to conquer structural steel. This specialized carriage is engineered for maximum productivity,and uniquely efficient in welding stiffeners via the ability to run two MIG/MAG torches simultaneously for continuous or intermittent (stitch) welding. The Beam Runner is trackless running directly on the workpiece. Purposely built for I-beams, H-beams, T-bars, and C-channels, the Beam Runner CDL delivers precise, repeatable results. The Beam Runner is powered by an 18V LiHD battery system that is interchangeable with your other Steelmax cordless tools. It delivers power for an entire shift without cable clutter and improves worksite safety. With programmable weld paths, skip lengths, and crater filling, this versatile tractor is your all-in-one solution for structural fabrication.
