WELDER: ARC HELVI UNIVERSAL 400 MMA

Three-phase DC welding units, on wheels, with cooling fan, suitable for welding all types of electrodes. Stepless control of the welding current by magnetic shunt. Made in Italy

* The FY 5500 series MIG semi-automatic gas shielded welding machines use the most advanced INFINEON IGBT inverter with dual full bridge soft switch circuit technology suitable for all posistion welding and for high speed welding of sheetmental and medium plates * This is a core technology to take advantage of the inverter poer source to realise the soft switching state of the no-load, short cercuit and load * This decreasess the switching stress and also increase the reliability of the unit * This unit also has the characteristics of Gas Matal Arc Welding (GMAW) and inverter technology with constant voltage and current output * Used mainly for the welding of ferrous metals such as copper, aluminum, stainless steel, high carbon steel as well as being used in the construction industry for pipe welding, structial steel, shipyards and machinery manufacturing *

* The TIG200D is a 240V DC Tig welder incorporating full TIG functionality * The HF hard start provides easy arc ignition leaving no tungsten inclusion and no contamination of the tungsten electrode * The DC MMA welding capability delivers a smooth and stable arc allowing easy welding with electrodes obtaining high quality welds including cast iron, stainless and low hydrogen *
