IMF – Medium Frequency Welding Inverters

Medium-frequency welding inverters (IMF) made by Isotron are the perfect choice for reliable, efficient and precise welding, integrating repeatability and speed to power savings.

About IMF

Developed with Brazilian technology, which assures easy and fast access to our support, either for product customization, installation, process and maintenance.

It enables easy and interactive coding of welding programs in its exclusive HMI on high-resolution graphical color touchscreen, providing simple and intuitive operation.

In addition, the customer of the IMF Inverter series relies on the Isotron’s experts to receive help on the best welding programming, aiming to achieve welds with extreme efficiency in detachment, excellent visual conditions, reliability and repeatability.

This means that you may count on quality support and service whenever you need.
