Designed for resistance spot welding, fusing and seam welding applications, Miyachi Unitek's family of DC-TECH High Frequency Inverter Power Supplies feature rated capacities of up to 300 KVA and high weld current outputs. Selectable output frequencies of 600, 800 and 1000Hz allow DC-TECH units to reduce electrode wear and part deformation by utilizing lower weld currents, shorter weld times and lower weld pressures than conventional AC welding.
