17240240 - ESAB 4k Ohm 25W Power Resistor Replacement

Technical Overview of the ESAB 17240240 Resistor

The ESAB 17240240 is a specialized power resistor designed for use within the internal circuitry of industrial welding equipment. With a resistance value of 4000 Ohms (4kΩ) and a power dissipation rating of 25 Watts, this component plays a critical role in voltage regulation, current limiting, or signal conditioning within the power source. Manufactured to ESAB's stringent quality standards, it ensures consistent electrical performance even under the thermal stress and duty cycles typical of heavy-duty welding operations.

Industrial welding machines rely on precise resistance values to maintain stable arc characteristics and protect sensitive control logic. A resistor with a 25-watt rating indicates it is built to handle significant thermal loads, likely featuring a wirewound construction on a ceramic core for superior heat dissipation and stability. When servicing ESAB equipment, utilizing the correct OEM part number (17240240) is essential to maintain the machine's safety certifications and operational parameters. This resistor is supplied as a single unit, ready for installation by qualified maintenance personnel.

Failure of a power resistor in a welding circuit can lead to erratic machine behavior, loss of arc control, or complete system shutdown. This replacement part restores the original circuit design specifications, ensuring the longevity and reliability of your capital equipment. It is suitable for specific ESAB models where this exact resistance and wattage combination is specified in the service manual.
