Machines Characteristics The DB2 Series Invert DC Resistor Spot welders applies new type power developed by IGBT invert technology, microcomputer control technology and modern electric power and electronic ***** feature high control precision, good welding processing, energy saving and efficient, and are specially suitable for point welding of copper, aluminum and other non-ferrous metal materials and alloy, as well ad high-quality point welding of fine parts. DC output:DC welders improve welding thermal efficiency, and are suitable for non-ferrous materials and some material hard to welding process is stable and welding quality is improved. Fast Response The power-on time＜1ms, *0times of common welders, that is ***** with capacitance energy storage welders, the controllable ***** is suitable for fine components welding, and high quality, precision and speed welding. Applying microcomputer control to ensure consistent ***** group welding parameter storage, parameter adjustment and welding cyclic panel indication simplify operation. *-phase load balance (models above DBZ***0)brings to high power factor. Being ***** power consumption is only 1/3 of the AC welders. Small-size, lightweight, suitable for robot applications.
