555 Pro 300 Mma Welding Machine

The 555 PRO 300 offers the same trusted reliability and smart control features as the PRO 400, tailored for medium-duty welding applications. It comes with built-in protection against over-current, over-voltage, and overheating, along with auto shut-down on overload. Its intelligent fan cooling system ensures extended machine life by preventing dust accumulation, and the LED display provides clear visibility of welding parameters. The one-knob system auto-adjusts current, ensuring smooth and precise welds.
Equipped with Hot Start and Arc Force for instant ignition, the PRO 300 also incorporates advanced IGBT soft-switch technology for a stable and smooth arc. It covers a current range of 20160 amps, suitable for thin and medium workpieces, and works with 6010, 6011, and 7018 electrodes. The machine is generator-friendly, lightweight, portable, and built for durability in workshops or field applications, making it an ideal solution for professional welders.
