The Thermion 71000-4.8 VS Feeder Assembly is a core component of the Precision Arc 4.8 twin wire arc spray system, designed for high-production industrial and field use. It features a modular, keyed plug-and-play construction, is detachable for confined spaces, and includes ergonomic and safety controls such as a dead-man switch. The unit feeds 3/16-inch (4.8 mm) wires at high deposition rates, with change-over kits available for other sizes, and uses VS Technology for automated wire feed speed adjustment. It includes low-friction roller bearing guides, integrated wire straighteners, and remote amperage/voltage controls at the feeder. The assembly requires a 650 Amp, 100% duty cycle power supply, compatible modular control boxes, and 90-110 psi air at 60 cfm.
