0349311759 - ESAB Tp199R 2K Ohm Replacement Potentiometer

Technical Overview of the ESAB Tp199R Potentiometer

The ESAB Potentiometer Tp199R 20A 2K (SKU: 0349311759) is a precision electrical component designed specifically for the maintenance and repair of ESAB welding power sources and wire feeders. As a variable resistor with a total resistance of 2,000 Ohms (2K), this potentiometer plays a critical role in the user interface of welding equipment, translating mechanical rotation into electrical signals that the machine's control board interprets to adjust output parameters.

Manufactured to ESAB's stringent OEM specifications, this component ensures linearity and durability that matches the original part installed at the factory. In industrial environments, potentiometers are often subject to dust, debris, and constant mechanical wear. The Tp199R is built to resist these environmental factors, ensuring a long service life and reducing the frequency of maintenance intervals. The "20A" designation in the product specification typically refers to a specific series rating or load characteristic relevant to the Tp199R model line, ensuring it can handle the control circuit currents found in heavy-duty welding machinery.

Technicians replacing this part should verify the resistance value matches the faulty unit. Installation typically involves a standard panel mount configuration. Using genuine ESAB parts like the 0349311759 guarantees that the calibration of the machine remains accurate, preventing issues such as drifting settings or non-linear response curves that can occur with generic replacements.
