300940 - Miller SubArc Strip Drive 100 Digital with Bracket

Precision Strip Cladding Drive System

The Miller 300940 SubArc Strip Drive 100 Digital Low Volt is a specialized component engineered for the demanding requirements of industrial strip cladding. Unlike standard wire feeders designed for cylindrical electrodes, this unit is specifically constructed to feed flat strip electrodes used in high-deposition Submerged Arc (SAW) and Electroslag (ESW) welding processes. This distinction is critical for applications requiring broad surface coverage and specific metallurgical properties, such as corrosion-resistant overlay on pressure vessels or wear-resistant hardfacing on industrial rolls.

Operating on a low-voltage digital platform, the Strip Drive 100 integrates seamlessly with Miller's family of SubArc Digital power sources and interface controls. This digital communication allows for precise speed regulation and instant feedback, ensuring that the deposition rate remains constant throughout the welding cycle. The unit is designed to handle the high torque and unique feeding mechanics required to move strip material smoothly without slipping or deformation.

This package includes a robust mounting bracket, facilitating easy installation onto welding manipulators, side beams, or custom automation fixtures. The inclusion of the bracket ensures rigid positioning, which is essential for maintaining the correct stick-out and arc characteristics during the cladding process. By utilizing genuine Miller OEM components, operators ensure compatibility and reliability in heavy-duty manufacturing environments.

Technical Application

This drive is intended for use in automated setups where consistent overlay thickness and dilution control are paramount. It supports both the high-heat input of Submerged Arc welding and the high-deposition, low-dilution characteristics of Electroslag welding. The low-voltage control architecture not only improves safety but also simplifies the cabling and integration with modern digital welding controllers.
