0191085105 - ESAB 5 Microfarad 400 Volt Replacement Capacitor

High-Performance Electrical Component for Welding Systems

The ESAB 0191085105 is a specialized capacitor designed to meet the rigorous electrical demands of industrial welding equipment. Rated at 5 microfarads (µF) and 400 volts, this component plays a critical role in the power regulation and filtering circuits of compatible ESAB power sources. Capacitors are fundamental to the smooth operation of inverter and transformer-based machines, helping to stabilize voltage, filter noise, and store energy for rapid discharge when the arc requires it. Using a capacitor with the correct capacitance and voltage rating is essential for the longevity of the machine's entire electrical system.

Manufactured to ESAB's strict quality standards, this OEM part ensures that the electrical characteristics match the original engineering specifications of your equipment. Generic capacitors may vary in their equivalent series resistance (ESR) or thermal tolerance, which can lead to premature failure or suboptimal arc performance. This 400V rated unit is built to handle the voltage spikes and thermal cycling common in heavy-duty welding environments, ensuring a long service life and reducing the frequency of maintenance intervals.

When sourcing replacement parts for high-value industrial machinery, precision is key. The 0191085105 provides the exact form factor and terminal configuration required for a seamless fit, eliminating the need for hazardous modifications or retrofitting. Whether used in a preventative maintenance schedule or as a critical repair component, this capacitor restores the electrical integrity of the welding power source, allowing it to deliver the consistent current required for high-quality welds.

Technical professionals understand that the reliability of a welding system is only as good as its smallest component. By choosing this genuine ESAB capacitor, you are investing in the continued operational efficiency of your fleet. It is suitable for specific ESAB models; please verify the part number against your machine's spare parts list or service manual to ensure compatibility.
