ARC 400
The ARC 400 is a high-efficiency, heavy-duty MMA welding machine engineered for industrial environments like shipyards, fabrication units, and foundries. Powered by advanced IGBT inverter technology and a 3-phase 415V±15% input, this machine delivers a wide output current range of 40–400A, adjustable arc force and hot start, and superior energy savings. A digital display, VRD safety feature, dust-free cooling, and rugged build with corner protectors make it the go-to unit for intensive welding applications.
Available in Pack: Single-unit pack with inverter power source, 2 quick plugs, and 1 allen key.
