0458063001 - ESAB 500A Hall Effect Current Sensor Replacement

Restore Your Welder's Performance

Is your ESAB welder acting up? If you are experiencing erratic arc behavior, fluctuating amperage readings, or if the digital display on your machine doesn't match what you are actually welding with, the culprit might be the current sensor. The ESAB Current Sensor 500A (0458063001) is the direct replacement part you need to get your machine back to running like new. This sensor is the "eye" of your welder's computer, telling it exactly how much power is being pushed to the torch.

When a current sensor fails, the machine is essentially flying blind. It might output too much power, burning through your material, or too little, causing the rod or wire to stick. In some cases, the machine might shut down completely to protect itself. Swapping out a faulty sensor is a standard repair procedure that can save you the cost of a new machine. This is a genuine ESAB part, meaning it will fit perfectly into the mounting bracket and plug directly into the existing harness without modification.

Don't risk your weld quality or your machine's safety with unverified aftermarket electronics. This 500A sensor is built to handle the heat and vibration of a shop environment. Whether you are repairing a MIG, TIG, or Stick power source that utilizes this specific part number, installing the correct sensor ensures that when you dial in 150 amps, you get exactly 150 amps at the arc. Get your equipment back in the fight with reliable OEM parts.
