407002-002 - Thermal Arc Fabricator 252i Bottom Drive Roll .023-.035 V-Groove

Product Overview

The Thermal Arc 407002-002 is a specialized Bottom Drive Roll engineered for the precise feeding of welding wire in industrial environments. Manufactured to strict OEM specifications, this component features a V-Groove geometry, which is the industry standard for feeding hard, solid wires such as mild steel and stainless steel. The groove dimensions are calibrated to accommodate wire diameters between .023 inches (0.6 mm) and .035 inches (0.9 mm), providing versatility for various fabrication tasks without the need for constant tooling changes.

Compatibility and Application

This drive roll is explicitly designed for the Thermal Arc Fabricator 252i multi-process welder. It serves as the bottom roller in the feed mechanism, working in conjunction with a corresponding top pressure roll to advance the wire through the gun liner. While V-Grooves are typically reserved for solid wires, the manufacturer indicates this specific roll is also capable of feeding flux-cored wires within the specified diameter range, offering operational flexibility for operators switching between processes.

Technical Construction

Constructed from hardened steel, the 407002-002 resists the abrasive wear caused by the continuous friction of metal wire. The precision machining of the V-profile ensures that the wire is gripped firmly without deformation, which is critical for maintaining a stable arc and consistent weld bead profile. Proper installation of this bottom roll is essential for the longevity of the wire feeding system and the prevention of feed issues such as slippage or erratic wire speeds.
