The Miller OBT 1200 SubArc Torch (043900) is a premier solution for heavy-industrial submerged arc welding (SAW) applications. Engineered by Miller Electric, this torch is designed to handle extreme welding parameters, boasting a current rating of 1200 Amps at a 100% duty cycle. This makes it an ideal choice for continuous, high-deposition welding operations found in shipbuilding, heavy fabrication, and pipe manufacturing. The torch is built to withstand the rigors of industrial environments while delivering consistent electrical conductivity and arc stability.
A key feature of the OBT 1200 is its concentric flux flow nozzle design. This engineering ensures that the granular flux is distributed evenly around the arc, providing superior atmospheric protection and slag formation. Proper flux coverage is critical in submerged arc welding to prevent porosity and ensure mechanical properties, and the OBT 1200 excels in maintaining this coverage even during long weld runs. The torch body is robustly constructed to manage the heat generated during high-amperage operation without compromising performance.
Versatility is central to the OBT 1200's design. It accommodates a wide range of wire diameters, from 1/16 inch (1.6 mm) up to 3/16 inch (4.8 mm), allowing fabricators to adapt to various plate thicknesses and joint configurations. The package includes the essential components required to get up and running, including the torch body, wire liner, flux nozzle, and wire inlet guide. Whether integrated into a manipulator system or a tractor setup, the Miller OBT 1200 provides the reliability and power necessary for demanding SAW processes.
