The MW Tools TEC220S electrode welding inverter delivers 220 A at 230 V and features a clear LCD display along with extensive welding accessories. This compact, lightweight unit offers intuitive operation with automatic current adjustment based on workpiece thickness and electrode diameter, ensuring stable, consistent welding performance. With a duty cycle of 30 percent at 220 A, it can handle multiple 3.2 mm and 4.0 mm electrodes in succession without interruption. The system includes 3 m and 4 m welding cables with a cross-section of 25 mm² and supports optional TIG welding with contact ignition. Advanced electronic arc controls include adjustable arc force to maintain arc stability when in contact with the molten pool, adjustable hot start for optimal ignition without spatter, anti-stick function to prevent electrode sticking at low currents, and VRD protection against electric shock in damp environments. Suitable for rutile, basic, stainless steel, and cast iron electrodes, the inverter offers protection against overload, overvoltage, and undervoltage. The package includes a sturdy shoulder strap, an electrode holder with a 4 m 25 mm² cable, a ground clamp with a 3 m 25 mm² cable, and a DX50 connector plug on the device. Additional duty cycles are 60 percent at 170 A and 100 percent at 120 A. Compatible electrodes include standard rutile-coated types in diameters from 2.0 mm to 4.0 mm with lengths from 250 mm to 350 mm, basic-coated electrodes in 2.5 mm diameter, and thick-walled rutile electrodes in various sizes, all available in weight configurations from 1.6 kg to 5.0 kg.
