Is a rectifier adopting the most advanced inverter technology. Welding power source can offer stronger, more concentrated and more stable arc. When stick and work piece get short, its response. Power cords extend to 700 feet still can use normally. Advanced IGBT inverter technology. Hot start, anti-sticking, force adjusts. Use on all of generator, also is very perfect. Very easy to starting and improvers. Very solid structure and professional configuration. Automatic compensation for voltage fluctuation, over-voltage protection, under voltage protection, over current protection, over load protection. 50% duty cycle at 180 amps. Ensures long time welding, the current range from 20-180 Amp, Very suitable for welding of various materials and projects. This is optimized to deliver a flawless weld, making spatter and post-weld cleanup almost non-existent. The strength of its components makes this a reliable work tool for professionals or personal use. Type: Stick Arc DC Inverter Welder. Nominal DC Open Circuit Voltage. Output Voltage: 27.2-Volt.
