Arc Runner Portable Programmable Welding Carriage

PRICE

The Steelmax® Arc Runner is a portable, programmable welding carriage designed to produce consistent, high-quality welds. The powerful magnetic base and closed loop electronic speed control provide speed stabilization in all positions. The unit enables weld bead geometry that is exact to the required specifications, substantially reducing costly over welding and decreasing filler metal usage.

The Arc Runner can be programmed in continuous or stitch welding modes. Two easy-to-use function buttons enable programming of weld length, distance between welds, reverse fill, crater fill time and other required patterns and parameters. The Arc Runner travels at full speed between stitches, which saves valuable welding time.

An optional pendulum torch oscillator is available for the Arc Runner to produce weave welds. The oscillator allows for precise control of weave width, weave speed and left/right side wall dwell.

Arc Runner’s micro processor allows for development, storage and reproduction of up to 40 different welding programs for various joint configurations and multi-pass, multi-layer welds. Once an optimum weld procedure is developed, stored and programmed, Arc Runner will repeat it over and over again.

Application Use Cases

The S14-M suits mechanical fabrication, transportation, and construction work where angled cuts matter as much as a clean edge. It handles pipe, plate, channel, conduit, angle iron, metal studs, rebar, and tubing, making it useful for structural steel fabrication, custom metal frames, and repeatable angle cuts on production runs. Its 1750W motor and portable 72 lb frame support both jobsite work and continuous shop use.

Frequently Asked Questions

The S14-M offers a wider +/-46° mitering range compared to the S14's 45°, plus a heavier cast-aluminum base for added stability. Both share the same 1750W motor, 14" blade, and pipe capacity, with the S14-M priced for its extra versatility.

The S14-M comes in both 120V/60Hz (SM-S-14-M) and 230V/50Hz (SM-S-14-M-230) versions, so it runs on standard shop power or 230V circuits depending on your facility's setup.

A newly designed 14" laser-cut TCT blade for mild steel is included. The 1" arbor bore accepts other compatible 14" blades, so operators can swap in one suited to aluminum, stainless, or thinner materials.

The S14-M miters up to +/-46°, letting operators dial in custom angles for fabrication layouts. The precision miter table locks at the set angle, delivering repeatable, accurate cuts across a production run.

At 72 lbs, the S14-M is portable enough for jobsite use while still built for shop duty. Steelmax positions it for both field and shop environments, making it a flexible pick either way.
