ST-165M is a rectifier incorporating the most advanced inverter technology. The welding power source can offer a more reliable， more concentrated， and more stable arc. When the stick and work-piece shorten， the response will be quicker. The welder uses a variety of electrodes， such as acid electrodes， alkaline electrodes， and cellulose electrodes (6010， 6011， 6013， 6014， 7014， 7018， etc.). The machine also works efficiently with generators. Power cords can properly function extended up to 700 feet. Specifications: Model: ST-165M.
