17240001 - 1 Ohm 25W Wire Wound Resistor Spare Part

Get Your Welder Back Up and Running with the Right Resistor

When your welding machine acts up, it stops your work dead in its tracks. Often, the culprit is a small but mighty electronic component buried inside the case. The ESAB 17240001 is a heavy-duty 1 Ohm, 25 Watt Wire Wound Resistor specifically designed to handle the power loads found in professional welding equipment. Unlike standard electronics store resistors, this wire-wound beast is built to take the heat and electrical surges that occur every time you strike an arc.

Why is this part important? Inside your welder, resistors like this one manage the flow of electricity. They might be helping to control the voltage, protecting sensitive chips, or dumping excess power when you stop welding. If this resistor burns out or cracks—often visible as a darkened spot or a break in the casing—your machine might not turn on, or the arc might become erratic and impossible to control. Replacing a blown resistor with this exact 25-watt, 1-ohm unit restores your machine to its factory performance.

Installation and Safety: This is a fixed resistor with a 5% tolerance, meaning it's precise enough for the job. It's a direct replacement for the part number 17240001 found in various ESAB models. Before you swap it out, remember the golden rule of welder repair: Unplug the machine and let it sit for a few minutes to allow any capacitors to discharge. Safety first! Once safe, swapping this resistor is usually a matter of desoldering the old one and soldering this new one in place, or screwing it into terminals depending on the mount.

Don't let a small part cost you a day's pay. Keep your equipment in top shape with genuine replacement parts. This resistor offers the durability and specs you need to trust your machine again. Whether you are fixing a MIG, TIG, or Stick machine that calls for this part, the 17240001 is the correct choice for a lasting repair.
