Manufactured with a pressed steel outer casing, lighter than traditional models at 20kg. Fully functional LCD front panel with easy to follow assisted set up. First, select type of welding, you will be advised the gas mixture and polarity recommended. Input electrode or wire thickness, completing the set up with the material thickness, you are then ready to start welding. Up to four set ups can be saved on the machine for fast loading. Inverter technology offers many advantages over traditional transformer type welders, giving greater duty cycles and more power factor efficiency. 3-in-1 Welder uses state-of-the-art technology to achieve MIG/TIG/MMA (Arc). Suitable for arc welding a variety of rods including rutile, basic and stainless. Fan cooled DC power supply for MIG and TIG, suitable to weld steel, stainless steel, copper, nickel, titanium and their alloys. Switchable between MIG, TIG* or MMA* welding modes (*optional extra torches required). Thermal overload warning tells you to switch off when it exceeds maximum temperature. Wire feed control for adjusting speed of wire fed through the torch during welding. Polarity change terminals allow for MIG or flux-cored welding. Includes 3m MIG torch, earth cable, gas hose, regulator and contact tips.
