674216 - ESAB 0.02 Microfarad 1kV Ceramic Disc Capacitor

Precision Electronic Component for Industrial Welding Equipment

The ESAB 674216 is a specialized ceramic capacitor designed for the rigorous demands of industrial welding power sources. In the complex architecture of modern inverter and transformer-based welding machines, capacitors play a critical role in signal filtering, noise suppression, and high-frequency arc stabilization. This specific component features a capacitance of 0.02 microfarads (µF) and a substantial voltage rating of 1000 Volts DC (VDC), making it suitable for high-voltage sections of the control or power circuitry where standard low-voltage capacitors would fail.

Constructed with a high-quality ceramic dielectric, this capacitor offers excellent stability and low losses, which are essential for maintaining the precision of the welding arc and the protection of sensitive semiconductor components. Ceramic capacitors are known for their non-polarized nature and superior frequency response, making them ideal for snubber circuits that protect transistors from voltage spikes, or for coupling high-frequency signals in TIG starting circuits. The 1000 VDC rating provides a significant safety margin against the transient voltage surges inherent in the welding process.

As a genuine ESAB replacement part, the 674216 ensures exact physical fitment and electrical compatibility with the original equipment manufacturer (OEM) specifications. Using generic components in sophisticated power electronics can lead to impedance mismatches or premature failure due to thermal stress. This OEM part is manufactured to meet strict tolerance standards, ensuring that the repair restores the machine to its factory performance levels. It is a vital component for maintenance personnel and electronics technicians tasked with troubleshooting and repairing ESAB welding systems.

Whether utilized in the primary inverter stage, the secondary output rectification stage, or the control board logic, this capacitor delivers reliable performance. Its robust encapsulation protects the internal ceramic element from environmental factors such as dust and humidity, which are common in industrial workshop environments. For professional repair and maintenance operations, stocking genuine ESAB electronic components like the 674216 is essential for minimizing downtime and ensuring equipment reliability.
