Description

Salient Characteristics: Thermion 71000-4.8 VS Feeder Assembly Part Description: 71000-4.8 VS Feeder Assembly 4.8 with VS Technology With Lubricating System Manufacturer: Thermion Associated System: Precision Arc 4.8 Twin Wire Arc Spray System 1. General Overview The Thermion 71000-4.8 VS Feeder Assembly is a core component of the Precision Arc 4.8 high-production twin wire metalizing system. It is specifically designed to feed large-diameter spray wires (such as zinc, aluminum, and zinc/aluminum alloys) smoothly and consistently in ultra-high production, industrial, and field environments. 2. Essential Physical and Design Characteristics • Modular Construction: Features a in. plug-and-play in. factory-built design, allowing for quick, toolless connections. Each fitting is uniquely keyed to eliminate connection errors. • Detachable and Portable: The feeder can be detached from its standard cart mount, making it suitable for use in highly confined spaces and small entrance areas(down to 24 inches). • Heavy-Duty Components: Constructed with heavy-duty, high-temperature machine components designed to withstand harsh shop or field environments.• Ergonomics and Safety: Includes an exclusive ergonomic handle design to reduce operator fatigue and a non-latching trigger that acts as a dead-man switch for instant emergency shutdown. 3. Essential Functional and Performance Characteristics • Wire Compatibility: Capable of running 3/16 in. (4.8 mm) diameter spray wires, yielding extremely high deposition rates (e.g., up to 190 lbs./hr. for Zinc). Change-over kits can adapt the system for other sizes like 1/8 in., 3/32 in., 2mm, or 1/16 in.. • VS Technology (Arc Voltage Drive / Variable Speed): Utilizes automated wire feed control technology to automatically adjust wire feed speed, maintain a perfect arc, eliminate arc shorting, and prevent coating defects caused by sputtering. • Lubricating System / Friction Reduction: Equipped with advanced, long-life wire drive assemblies featuring sealed roller bearings and roller bearing inlet guides. This low-friction mechanism mitigates drag on the wires as they enter the feeder, ensuring a smooth, non-slip feed without dry-friction binding. •Integrated Wire Straighteners: Heavy-duty wire straighteners are built into the drive assembly. These self-adjusting mechanisms remove the helix or kinks from spooled wire, ensuring flawless delivery to the spray head. • Remote Control Accessibility: Features remote amperage and voltage meters with integrated control mechanisms located directly at the feeder, allowing operators to make adjustments without returning to the main power supply. 4. System Compatibility and Operating Requirements • Power Supply: Designed to integrate with a 650 Amp, 100% duty cycle power supply (such as the Thermion DIM-650). • Control Box Compatibility: Pairs with Thermions modular control boxes (e.g.,71097-ASSY). • Air Consumption: Requires 90-110 psi at 60 cfm (using a 1/2 in. IPS/NPT connection) for optimal atomization and functionality.
