Genuine Miller 193920 Pointer Knob Replacement

Maintain the precision and functionality of your industrial welding equipment with the Miller 193920 Pointer Knob. This genuine OEM replacement part is engineered to meet the exact specifications of Miller Electric's high-performance power sources and wire feeders. A missing or damaged knob can make it difficult to accurately read settings or adjust parameters, potentially affecting weld quality. This replacement restores the original tactile control and visual reference points necessary for precise operation.

The knob features a 0.840-inch outer diameter, providing a comfortable grip for operators, even when wearing light work gloves. It is designed with a 0.250-inch (1/4-inch) inner diameter to fit standard potentiometer shafts found on compatible Miller equipment. The integrated pointer design allows for clear visibility of current settings against the machine's faceplate scale, ensuring operators can dial in the exact parameters required for the job.

Installation is straightforward and secure. The knob comes equipped with a single set screw that tightens against the control shaft, preventing slippage or accidental removal during transport and use. This mechanical fastening is essential for equipment that operates in high-vibration environments typical of welding sites.

This specific part is verified for use with the Miller STi 203 CE and Unitor UWI 202 CE arc welding power sources. Additionally, it serves as a direct replacement for knobs on the rugged SuitCase 8VS and S-74DX CE series wire feeders. Using genuine Miller parts ensures material compatibility and longevity, protecting your investment in premium welding machinery.
