951676 - Miller SubArc DC 1000 Digital Portable System

Complete Mobile Submerged Arc Welding Solution

The Miller SubArc DC 1000 Digital Portable Welding System (951676) represents a pinnacle in heavy industrial fabrication technology, offering a fully integrated, self-contained solution for submerged arc welding (SAW). Designed to address the logistical challenges of positioning heavy welding equipment around large workpieces, this system combines a high-output DC power source, a precision column and boom, and advanced digital controls onto a robust mobile platform. With a rated output of 1000 Amps at 44 Volts and a 100% duty cycle, this machine is engineered for the most demanding applications, including pressure vessel manufacturing, pipe fabrication, and heavy structural steel construction.

At the core of the system is the SubArc Digital Series Interface, which provides operators with granular control over the welding process. The digital feedback loop ensures consistent wire feeding and voltage stability, which is critical for maintaining weld quality in submerged arc processes where the arc is not visible. The system features a motorized column that offers 44 inches (1,117 mm) of vertical travel, controlled via a pendant, allowing for effortless height adjustments. Complementing this is a manual telescoping boom that provides 31 inches (787 mm) of horizontal reach, and manual cross slides that offer nearly 8 inches of fine adjustment in both vertical and horizontal planes. This flexibility ensures that the OBT 1200 torch can be positioned with extreme accuracy, reducing setup time and improving weld integrity.

Mobility is a key feature of the DC 1000 Digital Portable System. The unit is equipped with heavy-duty caster wheels and built-in fork pockets, allowing it to be easily maneuvered across the shop floor or transported between job sites. This "bring the welder to the work" philosophy significantly enhances productivity in environments where moving the workpiece is difficult or impossible. The package is truly turnkey, including the SubArc Wire Drive 400, a flux hopper with a valve, a wire reel assembly, and all necessary control cables. By consolidating these components into a single, mobile footprint, Miller Electric delivers a system that maximizes uptime and simplifies the complexity of heavy industrial welding.
