MMAW/ SCRATCH TIG WELDING MACHINES: 3-Phase

Z-400 series machines are 400A IGBT based inverter mmaw/tig welder. MMAW/TIG (Lift TIG) suitable for all weather indoor and outdoor welding applications. Lightest among the Indian manufacturers (415A power source weighs 20Kgs only) and coupled with a robust sheet metal design makes it a preferred choice of the welders. It is equipped with all the essential features for MMAW - anti stick, arc force and hot start to handle MMA electrodes of any class - basic, rutile or cellulosic up to 6.3 mm size. The micro-controller based design ensures consistent performance for any class of electrode even at worse power conditions - input voltgage as low as 360V or as high as 480V. In-built protections are provided against thermal overloading, single phasing, over/under voltage and harmonics. Pf is close to unity and saves electricity up to the extent of 40 to 50% over the conventional rectifiers.
