950584 - ESAB Replacement Skirted Control Knob - 1/4 Inch Shaft

Genuine ESAB Replacement Component

The ESAB 950584 is a specialized skirted control knob designed to replace damaged or missing interface components on compatible ESAB welding power sources and wire feeders. In the realm of industrial equipment maintenance, the integrity of the user interface is critical for precise operation. This knob is engineered to fit a standard 0.25-inch (1/4") shaft, a common specification for potentiometers and rotary switches used in heavy-duty welding machinery. The alphanumeric designation in the part description suggests specific dimensional attributes: a 0.25-inch shaft fitment, a skirted base for debris deflection and aesthetic integration, and a durable plastic composition suitable for electrical isolation.

Using genuine OEM parts like the 950584 ensures that the mechanical interface between the operator and the machine's internal electronics remains consistent. Generic knobs often fail to seat correctly on the shaft (D-shaft vs. round shaft vs. splined) or lack the appropriate skirt depth to cover the mounting hardware of the potentiometer. This ESAB component features a skirted design which serves a dual purpose: it provides a visual transition between the panel and the knob, and it helps prevent dust, metal shavings, and grinding particulate from easily entering the shaft bushing mechanism. This is particularly important in welding environments where conductive dust is prevalent.

The construction utilizes high-impact plastic, selected for its resistance to the thermal fluctuations and rough handling typical of a fabrication shop. Whether used for adjusting wire feed speed, voltage, or inductance, the tactile feedback provided by a properly fitted knob is essential for fine-tuning weld parameters. Maintenance personnel and equipment repair specialists should verify the specific parts list of their ESAB equipment to confirm compatibility with part number 950584 before installation. Restoring the control panel with authentic parts maintains the equipment's resale value and operational safety standards.
