The ESAB 17300020 is a high-specification electrical component designed for use within ESAB industrial welding equipment. Identified as a "RES RW FIXD ST 300W 10% *20.00", this component is a fixed wirewound resistor capable of handling significant power loads. With a power rating of 300 Watts, it is engineered to dissipate heat effectively while maintaining stable electrical performance under load. The resistance value is calibrated to 20.00 Ohms with a standard tolerance of 10%, making it suitable for various power regulation, current limiting, or dynamic braking applications within the welder's internal circuitry.
Wirewound resistors like the 17300020 are constructed by winding a metal wire, typically a nickel-chromium alloy, around a ceramic or fiberglass core. This design is preferred in industrial electronics for its superior pulse handling capability and high-temperature stability compared to other resistor types. In the context of welding machinery, these resistors often manage inrush currents or act as bleeders for capacitors, playing a critical role in the safety and longevity of the power source. Using non-OEM substitutes with incorrect wattage ratings or thermal coefficients can lead to premature failure or overheating.
This part is supplied directly by ESAB, ensuring it meets the original design specifications of your equipment. When replacing power resistors, it is crucial to verify the part number 17300020 to ensure physical fitment and electrical compatibility. The "ST" designation likely refers to a standard mounting configuration, allowing for straightforward installation into the existing chassis mounts of the welding machine. Whether you are performing routine maintenance or troubleshooting a power fault, this genuine ESAB resistor provides the reliability expected from top-tier welding equipment manufacturers.
