TRAFILUX Hero 400 MMA This is a lightweight, portable invention that provides the ability to weld with covered electrodes. The device has a number of innovative technological solutions, more extensively described in the product features. Hero 400MMA is suitable for use in household and workshop conditions. It is ideal for repair work, assembly, and field tasks. The advantage of the device is the stepless adjustment of welding current, arc dynamics (ARC FORCE) in addition, the device has a VRD module, designed to increase the safety of the user, working in a dangerous environment that increases the risk of electric shock. In particular, work in places where we have to deal with high humidity, and the welder's contact with liquids, for example, during work on sewers, work on excavations or in thermal power plants. The device is used for welding steel, including stainless steel, heat-resistant steel and cast iron. The design advantage of the device is transistors made with IGBT technology. The characteristics of this type of transistors are, lower power consumption, less electromagnetic interference, with higher efficiency and a stronger and more stable welding arc. Features Waterproof technology - the device is resistant to moisture and water flooding. Intelligent power voltage detection system from 110V to 280V Energy-saving mode - after a few minutes at rest, the device will automatically turn off the fan and go into stand-by mode. Touching of the potentiometers awakens the device and returns it to operation. Built-in voltage stabilizer, allow operation with generators and the use of long power cables (up to 100m.) and long welding cables (up to 50m.). welding cables (up to 50m.) VRD - built-in VRD module that reduces the idle voltage from 75V to 14V. Ability to weld with electrodes in diameters: 2.5-6.0mm along with alkaline electrodes. TIG LIFT - the possibility of welding in the TIG method using a handle with a gas valve gas in the handle LED display ARC FORCE - infinitely adjustable arc dynamics - choice between soft arc (diffused) arc giving a shallower depth of fusion, useful when welding thin metal sheets, and hard (concentrated) arc giving a deep fusion into the material. Infinitely adjustable welding current and arc dynamics. Thermal protection system to prevent overheating of the device. Meets CE standards Equipment : Ground wire Electrode cable Manual in Polish
