Maintain the precision and functionality of your Miller welding equipment with the Miller 174991 Knob, Pointer. This essential replacement part is designed to restore the tactile control and visual accuracy of your machine's interface. Over time, control knobs in industrial environments can become worn, cracked, or lost due to heavy usage and transport. Replacing them with genuine OEM parts ensures that your equipment remains easy to operate and safe to handle.

The Miller 174991 features a 1.250-inch outer diameter, providing a substantial grip surface that is easy to manipulate even when wearing welding gloves. The knob is molded with a distinct pointer, allowing operators to quickly verify settings at a glance—a critical feature for maintaining consistent weld parameters. It is engineered with a 0.250-inch (1/4 inch) inner diameter, making it compatible with standard potentiometer shafts found on various Miller power sources and wire feeders.

Installation is straightforward and requires no special tools. The knob utilizes a spring clip mechanism (included) that creates a friction fit against the shaft. This design ensures the knob stays securely in place during operation but can be removed if maintenance on the underlying control pot is required. By choosing genuine Miller parts from Josef Gas, you are guaranteed a component that meets the original factory specifications for fit, finish, and durability.

Whether you are repairing a damaged unit or refurbishing older equipment, this pointer knob is a small but vital component in keeping your welding operations running smoothly. Ensure your voltage, amperage, or wire speed controls are precise and reliable with this high-quality replacement.
