LI'L RUNNERTM Automatic Fillet Welder by STEELMAX®

LI'L RUNNERTM Automatic Fillet Welder by STEELMAX® creates consistent, high-quality welds and helps deliver big savings on any job that demands continuous welds, in a fraction of the time required by hand welding.

With its lightweight, compact design, all-wheel drive and magnetic force traction, the LI'L RUNNER provides stable, non-stop travel at user-regulated speeds. reliable traction and consistent speed enables the LI'L RUNNER to produce weld bead geometry to your exact specifications, reducing costly over-welding and decreasing filler metal use by up to 60 percent. 

Quick, Easy Setup and Operation

You have complete command of your welding process from start to finish with the LI'L RUNNER. Its positive magnetic traction and self-guiding roller arms eliminate the need for operating track. The magnetic-adhesion release lever permits easy placement and adjustment on a work piece, reducing set-up time and improving productivity.

The LI'L RUNNER rapid clamp torch holder mechanism works with all major brands of MIG / MAG torches and is coupled with a screw-drive cross slide for precise torch adjustment. Combine this exact torch placement with faster, user-regulated speed, and the LI'L RUNNER can significantly reduce weld defects and costly piece rework compared with hand welding.


Great Flexibility in a Small Package

Weighing just over 17 pounds, the LI'L RUNNER can be carried virtually anywhere on the job. The positive magnetic traction provides the versatility to handle long, straight continuous welds or permit out-of-position use, including on a vertical piece of steel. The LI"L RUNNER also finishes lids and bottoms with no attachment, and horizontal seams are completed with an optional arm attachment. All of these welds can meet your specifications with minimal distortion thanks to the LI'L RUNNER welder's consistent heat input and efficient use of filler metal. 

The LI"L RUNNER moves operators away from heat and fumes, reducing their exposure, as well as reducing the fatigue and repetitive stress associated with hand welding. With its speed, reliability and flexibility in producing high-quality continuous welds, the LI'L RUNNER Automatic Fillet Welder can help you keep productivity moving.
