The HG500 is a versatile and powerful 5-in-1 welding machine specially designed for home DIY or maintenance projects. It can be used to weld MIG (GMAW), Stick (SMAW), Gasless (FCAW), and TIG (GTAW). The HG500 also allows you to cut at the same time. Suitable for both home DIY and industrial projects. 4.3high-pixel LCD control screen that quickly and easily walks the user through setup,smoothly flow through the on-screen menu system and choose the setting.Digital control to choose welding mode, material, welding wires, tungsten rods, electrode and workpiece thickness.Color LCD display easy to read and set amperage and wire speed for repeatable welds every time. It has an advantage for stick welding. It includes a voltage reduction device (VRD), which improves your safety when stick welding by reducing the open circuit voltage (OCV) to safe levels. As soon as you strike an arc, the OCV will rise to the necessary levels to keep the arc going. But, when you are not welding, the OCV will drop to about 7V. The VRD function prevents accidental operator electrocution in wet, damp, and cramped areas.
