Using inverter technology, Ronix offers the RH-4640 welding machine for more compact and efficient operation. The device uses high-frequency inverters for fast switching between AC and DC. This way, you will have a smoother welding current and, consequently, better control over the entire welding process. This allows you to work best with various types of metals and different thicknesses.
The Ronix RH-4640 welding inverter is also portable and quite lightweight, so you can easily carry it to different work locations.
