266591 - Miller Encoder Control Knob 1.250 Dia Push-On

Restore Precision Control to Your Miller Welder

The interface of your welding machine is your primary connection to the arc. When control knobs become worn, loose, or go missing, making precise adjustments to voltage, wire feed speed, or amperage can become frustrating and inaccurate. The Miller 266591 Encoder Knob is a genuine replacement part designed to restore the tactile feel and reliability of your machine's front panel controls.

Exact Dimensions for Perfect Fit

This knob is engineered with a specific 6mm inner diameter (ID), sized perfectly to fit standard encoder shafts found on many modern Miller power sources. The 1.250-inch outer diameter offers a substantial surface area, making it easy to grip and rotate even when wearing thick welding gloves. The size is optimized to provide enough leverage for fine-tuning settings without being obtrusive on the control panel.

Tool-Free Installation

Maintenance in a busy shop needs to be quick. This encoder knob features a push-on design with an internal spring. There are no tiny set screws to lose or tighten. The internal spring creates friction against the D-shaft or round shaft of the encoder, holding the knob firmly in place during operation while allowing for removal if the machine needs to be serviced. Simply align the knob and push firmly until it seats against the panel.

Durability for Industrial Environments

Welding environments are tough on equipment. Plastic components can become brittle over time due to heat and UV exposure, or damaged by impact. Using genuine Miller replacement parts ensures that the materials used are tested for compatibility with the industrial environment. This knob is built to withstand daily use, ensuring that your ability to control your arc remains consistent shift after shift.
