C904627006 - ESAB Replacement Push Button XB6EAA21C Black 1NO

Technical Overview of the ESAB C904627006 Push Button

The ESAB C904627006 is a specialized replacement push button designed for the control interfaces of various ESAB welding power sources and industrial equipment. Identified by the industry-standard reference XB6EAA21C, this component is a monolithic, circular push button featuring a 16mm mounting diameter, making it suitable for compact control panels where space is at a premium. The unit is engineered with a spring-return mechanism and a flush black actuator, providing tactile feedback and reliable operation in industrial environments.

Electrically, this switch is configured with a Single Pole Single Throw (SPST) Normally Open (1 NO) contact block. The contacts are designed for slow-break operation, ensuring consistent electrical connectivity for signal circuits within the welding machine's logic board. The component is rated for durability, capable of withstanding the repetitive actuation common in high-volume welding operations. Its construction meets IP65 standards, offering significant protection against the ingress of dust and low-pressure water jets, which is critical for maintaining equipment longevity in dusty workshop environments or field sites.

Procuring genuine ESAB spare parts like the C904627006 ensures compliance with the original equipment manufacturer's specifications. Using non-OEM substitutes in complex welding circuitry can lead to fitment issues or unreliable signal transmission. This specific button is often found in the front panel assemblies of MIG, TIG, and multi-process machines, serving functions such as menu selection, parameter adjustment, or process initiation. Maintenance teams should verify the specific part number in their equipment's spare parts list before ordering to ensure compatibility.

Installation of the XB6EAA21C is straightforward for qualified technicians. The unit fits into a standard circular cutout and secures from the rear, ensuring a flush and professional finish on the machine faceplate. The terminals are designed for secure wiring, minimizing the risk of vibration-induced disconnection during machine operation.
