Miller Electric Mfg. LLC and Hobart Brothers LLC have announced the launch of the SubArc Hercules system, a combination of the XMT 450 SubArc Hercules power source, SubArc Hercules torch, and SubCOR metal-cored wire that is designed to increase deposition rates and reduce welding time by an average of 30%.
Along with increasing throughput, the SubArc Hercules system offers consistent weld beads with enhanced mechanical properties, making it suited for applications in the pressure vessel, process pipe, structural steel, shipbuilding, and wind tower industries. The system is engineered for use on long, multipass welds, as well as large groove welds, high-speed fillet welds and lap joints, and weldments sensitive to high heat input.
,ÄúThe SubArc Hercules system is an excellent fit for operations looking to gain higher deposition rates and faster travel speeds without compromising weld quality,,Äù said Louise Gasper, product manager at Miller. ,ÄúThe system consistently outperforms standard DCEP and AC solid wire submerged arc welding, allowing for improved efficiency.,Äù
The SubArc Hercules system can be added to any existing Miller SubArc DC or AC/DC digital power source or legacy 14-pin SubArc machine. The system includes the XMT 450 SubArc Hercules, a secondary 450-amp submerged arc power source that features a modified software that generates lower voltage (1 to 10 volts), and provides an electrical current to condition the wire during the Hercules process. The SubArc Hercules switch kit allows operators to easily enable the process with the flip of a switch and quickly alternate to a standard submerged arc process.
Once the Hercules process is activated, the SubArc Hercules air-cooled torch provides resistive conditioning of the wire by way of two contact tips,Äîan upper preheat contact tip (standard for Miller OBT 600 MIG guns) and a lower contact tip (standard for Miller OBT 1200 MIG guns). This contact tip combination and preheating results in high deposition rates, while also offering smooth wire feeding at higher temperatures.
The Hobart SubCOR metal-cored wire was specifically formulated to achieve those high deposition rates while maintaining consistent arc stability. The wire is available in five American Welding Society (AWS) classifications in 1/8" and 5/32" diameters with tensile strengths ranging from 70 to 110 KSI.
