Essential Repair Part for Miller Welders

Keep your welding equipment in top condition with the Miller 111644 Strain Relief Bushing. This small but mighty part plays a huge role in the safety and durability of your machine's power delivery system. Designed to fit into a 0.875-inch mounting hole, it provides a secure anchor point for cables entering or exiting the welder or wire feeder. Whether you are refurbishing an older machine or replacing a broken cord grip, this genuine Miller part is the exact replacement you need for a professional repair.

Protect Your Wiring from Damage

The primary function of the 111644 bushing is to absorb the mechanical stress placed on power cords during daily use. In a busy shop, cables are frequently tugged, stepped on, or dragged. Without a proper strain relief, these forces are transferred directly to the delicate electrical connections inside the machine, leading to loose wires, short circuits, or intermittent power issues. Additionally, this bushing prevents the cable insulation from rubbing against the metal cabinet, preventing dangerous arc faults and exposed conductors.

Specifications and Compatibility

Before ordering, it is important to verify the dimensions of your cable and the mounting hole on your machine. This specific bushing is designed for:

• Mounting Hole Size: 0.875 inches (approx. 22mm)
• Cable Diameter Capacity: 0.370 inches to 0.430 inches

It is commonly used across various Miller power sources and accessories. If your serial number lookup indicates part number 111644, this is the correct item to restore your equipment to factory specifications.

Quick and Effective Solution

Don't let a 50-cent problem turn into a 500-dollar repair. A missing or broken strain relief is often overlooked until it causes a major failure. Installing the Miller 111644 is a quick, low-cost preventative measure that protects your investment. Made from durable materials, it locks firmly into place and grips the cable tightly, ensuring that your welder is ready for heavy-duty work without the risk of cable failure.
