0458063006 - ESAB 0458063006 Current Sensor 19CS1 300A

Restore Your Welder's Accuracy and Stability

Is your ESAB welder acting up? Are you seeing erratic numbers on the amperage display, or is the arc fluctuating wildly despite steady hands? The culprit might be your current sensor. The ESAB 0458063006 Current Sensor 300A (19CS1) is the genuine replacement part you need to get your machine back to running like new. This small but mighty component is the "eyes" of your welder's computer—it tells the machine exactly how much power is being pushed to the torch or stinger.

When a current sensor fails, your welder is essentially flying blind. You might experience issues where the machine refuses to weld because it thinks there is no current, or conversely, it might run "hot" because it can't sense that it has already reached the set amperage. In some cases, a bad sensor will trigger a system error code that shuts the machine down entirely to protect the internal electronics. Swapping out a faulty sensor for this authentic ESAB 19CS1 unit is often the fix for these frustrating problems, saving you the cost of replacing the entire machine.

Don't gamble with aftermarket electronics when it comes to your power source. Generic sensors may look similar but often have different resistance values or sensitivity ratings, which can lead to dangerous over-current situations or poor weld characteristics. This OEM part is designed specifically for your ESAB equipment, ensuring a plug-and-play repair. Whether you are a professional repair shop or a welder fixing your own rig, this 300A sensor provides the reliability and accuracy required for high-quality fabrication work. Get your arc stability back and trust your digital display again with a fresh sensor.
