OVERVIEW

Automate Your Welding with the Miller SubArc Digital 3-Wheel Tractor

The Miller SubArc Digital 3-Wheel Tractor Package (951755) is a premier solution for heavy industrial welding applications requiring the high deposition rates and deep penetration of the submerged arc process. Designed to integrate seamlessly with Miller's SubArc DC and AC/DC Digital Series power sources, this self-propelled tractor system brings automation and consistency to your fabrication floor. By mechanically regulating travel speed and wire delivery, it eliminates the variables associated with manual welding, resulting in superior weld quality and uniformity essential for critical infrastructure projects.

Superior Mobility and Handling

Engineered for versatility, the tractor features a stable 3-wheel configuration that glides smoothly over large workpieces. It includes a locking front wheel that can be secured to follow a specific path for long, straight seams or unlocked for manual guidance. A key feature for operators is the intuitive foot- or hand-operated clutch. This mechanism allows for instant engagement of the drive system for welding and quick disengagement for freewheeling, making repositioning the unit effortless and reducing operator fatigue.

Digital Integration and Control

The package includes the SubArc Tractor Interface Digital, which serves as the command center for the system. It provides a single, easy-to-operate control point for both the power source and the tractor, ensuring that your set travel speeds and welding parameters are maintained with digital precision. This synchronization is vital for achieving consistent bead profiles in demanding applications like shipbuilding and pipe fabrication. Additionally, the system operates on a 24 VAC control voltage, prioritizing operator safety without compromising performance.

Built for the Toughest Jobs

Durability is standard with the Miller SubArc package. All major components, including the interface controls and the SubArc Wire Drive 400 Digital, are IP23 rated. This protection ensures reliable operation even in harsh environments where dust and moisture are present. The tractor is designed to hold a 60 lb (27 kg) wire reel, significantly reducing the frequency of wire changeovers and keeping your production line moving. Complete with the heavy-duty OBT 600 Torch, wire straightener, and flux hopper, this package is ready to tackle the most challenging heavy fabrication tasks.
