252443 - Miller 252443 Current Sensing Transformer 200:1 Ratio

Genuine Miller 252443 Current Sensing Transformer

The Miller 252443 XFMR is a specialized current sensing transformer designed to maintain the precision and reliability of your Miller welding equipment. As a critical component in the feedback loop of modern welding power sources, this transformer steps down the high welding current to a manageable signal level that the machine's control board can interpret. With a specific ratio of 200/1, it ensures that the amperage displayed and regulated by your machine matches the actual output at the arc.

Using genuine Miller Electric replacement parts is essential for preserving the integrity of your equipment. The 252443 transformer is engineered to meet the exact electrical and physical specifications required by compatible Miller models. This ensures not only a perfect physical fit inside the cabinet but also the correct electrical characteristics needed for stable arc performance. Inaccurate current sensing can lead to erratic welding behavior, poor heat control, and potential damage to other internal components.

This component is typically found in inverter-based or advanced solid-state welding machines where precise current control is paramount. Whether you are performing routine maintenance or troubleshooting a fault code related to current output, installing the correct OEM transformer is the best way to restore factory performance. Trust Josef Gas to supply authentic Miller parts that keep your industrial operations running smoothly.

Key Technical Features

The transformer features a robust design capable of handling the thermal and electrical stresses found inside industrial welding power sources. Its 200:1 ratio is calibrated for specific control boards, making it non-interchangeable with transformers of different ratios. Always verify your machine's parts manual or serial number to ensure this specific SKU is the correct match for your welder.
