0558001818 - ESAB Replacement Ribbed Control Knob - 1.37 Inch Diameter

Restore Precision Control with the ESAB Ribbed Knob

Maintaining the functionality of your welding and cutting equipment is critical for achieving consistent results. The ESAB Ribbed Knob (0558001818) is a genuine OEM replacement part designed to restore the tactile control interface of your machine. Over time, control knobs can become cracked, stripped, or lost in busy industrial environments. This replacement ensures that you can once again make precise adjustments to voltage, amperage, or wire feed speed with confidence.

This specific knob features a 1.37-inch diameter, providing a substantial surface area that is easy to locate and manipulate without looking away from your work. The ribbed texture along the circumference is a key design feature, specifically engineered for the welding industry. It allows operators to maintain a secure grip and make fine-tuned adjustments even while wearing thick leather welding gloves. A smooth knob can be difficult to turn with protective gear, but the ribbed design ensures non-slip operation.

Designed to fit a standard 1/4-inch shaft, this knob is compatible with a variety of ESAB power sources and control units. Whether you are repairing a MIG welder, a plasma cutter, or a multi-process machine, using genuine ESAB parts guarantees that the fit and finish match the original specifications. The durable plastic construction is resistant to the heat, dust, and minor impacts common in workshop settings, ensuring a long service life.

At Josef Gas, we understand that small parts play a big role in your productivity. A missing knob can turn a simple adjustment into a frustrating task requiring pliers or guesswork. By installing this genuine ESAB replacement, you protect the underlying potentiometer shaft from damage and restore the professional appearance and functionality of your equipment.
