17240003 - ESAB 25W 3 Ohm Wire Wound Resistor Replacement Part

Get Your ESAB Welder Back Up and Running

When your welding machine goes down, production stops, and every minute counts. The ESAB 17240003 is the genuine replacement resistor you need to fix specific electrical faults in your ESAB power source. Electrical components like resistors can fail due to age, heat cycles, or power surges, often resulting in a machine that won't strike an arc, won't feed wire correctly, or simply won't turn on. By choosing this genuine ESAB part, you are ensuring that your repair is permanent and reliable, rather than risking a repeat failure with a generic component that might not handle the rigorous demands of a welding environment.

This 25-watt, 3-ohm resistor is a heavy-duty component built to withstand the heat and vibration typical of a workshop or job site. It uses wire-wound technology, which is the gold standard for power handling in industrial electronics. Whether you are a professional repair technician or a welder performing your own maintenance, installing the correct OEM parts is the best way to protect your investment. A resistor might look like a small part, but it plays a big role in regulating the power inside your machine. Using the wrong spec could lead to erratic arc performance or further damage to expensive control boards.

Installation typically requires soldering the component onto a circuit board. We recommend disconnecting all power to the machine and discharging any capacitors before attempting replacement. Once installed, this 3-ohm resistor will restore the electrical balance to your machine's circuit, helping you get back to laying beads with the consistency and quality you expect from ESAB equipment. Don't settle for guesswork; stick with the part number specified in your machine's manual to ensure a perfect fit and function.
