MICOR TECHNOLOGY What is it? MIcro... COntrolled..Ṙesonant... What does it do? Technically Stores Voltage and Power for exceptional welding performance. The Turbo Boost Effect... Enables variable inverter operating frequency up to 200 KHz for the ultimate welding process control. Delivers absolute precision like clockwork with no sudden switching. Reduces Inverter size and weight for improved portability. Welding control managed by six Micro-controllers monitoring current and voltage at 1.5 million times per second. How good is the Performance? Delivers Delivers the ultimate performance and perfect welding characteristics for arc welding electrodes up to 3/16 inch. Delivers best in class vertical up/vertical down-welding of cellulose 6010 electrodes. Delivers a consistant, smooth, stable arc even when using cables up to 200 yards long. Delivers exceptional starting and arc control for MIG and Fluxcored welding process. MICOR Turbo Boost Effect. The Ultimate Performance. New MICOR technology delivers an optimized performance welding curve and acts like the turbocharger in a car: maximum power is developed from a very small power plant. ArcMaster 401S and 401MST deliver significant performance improvements over traditional inverter power supplies. Perfect Stick welding including cellulose 6010 and superior MIG /Flux Cored welding (Arcmaster 401MST). Conventional Inverter Technology: MICOR Inverter Technology: Voltage Reserve Inverter Characteristic Curve Standard Characteristic Curve MICOR Voltage Reserve MICOR Characteristic Curve Turbo Boost Effect Maximum Power from the smallest power source Standard Characteristic Curve Voltage and power reserves are small for conventional inverters. The welding process can become quickly unstable. Particularly for the critical, low current intensities, MICOR inverters build up a high voltage and ensure maximum stability. page 2 Tweco.com
