235740 - Miller MDX-100 Consumable Kit (.030/.035)

Optimized Performance for MDX-100 Systems

The Miller 235740 MIG Accessory Kit is a specialized consumable package engineered for the MDX™-100 MIG Gun. This kit is essential for operators utilizing Miller's AccuLock™ MDX™ system, which is standard on popular machines such as the Millermatic® 141, Millermatic® 211, Multimatic® 215, and Multimatic® 220 AC/DC. The components within this kit are manufactured to strict OEM tolerances, ensuring seamless integration with the torch assembly and maintaining the high-performance standards expected from Miller Electric equipment.

AccuLock™ MDX™ Technology

At the core of this kit is the AccuLock™ MDX™ consumable system. Unlike legacy MIG consumables, AccuLock components are designed to lock the contact tip in a fixed position relative to the liner. This concentric alignment significantly reduces wire drag and feeding friction, which is critical for maintaining a stable arc and preventing burn-back. The diffuser and nozzle geometry are optimized to channel shielding gas effectively, providing superior coverage and reducing porosity in the weld pool.

Comprehensive Maintenance Solution

This kit addresses the most common maintenance needs for light industrial fabrication and hobbyist applications. It includes a supply of both .030-inch and .035-inch contact tips, covering the most frequently used wire diameters for mild steel welding. The inclusion of a fresh gas diffuser and nozzle allows for a complete front-end overhaul, restoring the gun to factory-like performance. All components are housed in a compartmentalized plastic case, protecting the copper and brass parts from environmental contaminants and physical damage during storage.

Technical Specifications

The kit supports the MDX-100 gun rated at 100 amps. The contact tips feature a tapered design for better visibility and gas flow. The nozzle is a standard flush type, suitable for a wide range of welding positions and joint configurations. By using genuine Miller consumables, users ensure that the thermal conductivity and electrical transfer properties of the gun remain consistent, minimizing downtime associated with feeding issues.
