ARC500IJ DC Inverter Welding Machine

In simple terms, an inverter is an electronic system for voltage regulation. In the case of an inverter welding machine, it converts AC power supply into a lower usable output voltage - for example, from 240V AC supply to 20V DC output.DC welding is the preferred form of welding for most applications. Compared to AC welding, DC tends to have a smoother welding output, less spatter, and a more stable arc. It also penetrates more into weld metal, which offers a stronger bond than AC welding in most cases.
