The Steelmax Arc Runner is a portable, programmable welding carriage that can produce consistent, high-quality welds through stored welding programs. It uses a magnetic base and electronic speed control to stabilize welding speed. Operators can program welding patterns, lengths, and speeds through two buttons. The carriage repeats optimal welds and improves productivity over manual welding. Optional accessories allow for dual-torch, extended reach, and guided welding on various joint geometries.
