Single / Dual Cross Bar Grating Welding

Energy Efficient Three Phase Inverter DC Output Current Solution Three phase balanced input with constant DC output, 70% energy saving can be achieved compared with standard Single Phase AC machines! Low connected load of 800kVA for dual bar welding with primary current being as low as 1400A! Energy Efficient German Bosch Rexroth Inverter DC Power Supply The German Bosch Rexroth Inverter DC power supply helps making reliable welds with the primary current control and constant output current. High Return on Investment Low Energy Cost and Efficient Production With 70% energy-saving percentage, it could save up to US$20,000 in energy cost per year and have low connected load requirement compared with AC machine. High Production Efficiency Preloading System Without stopping the machine, operator loads the bearing bar onto the preloading system for auto feeding into the welding station. Safety and efficiency enhanced. Save Labour & Increase Safety Cross Bar Auto Loading System The pneumatic auto loader accurately feeds and positions two twisted bars onto the welding position prior to welding. Stable & Excellent Welding Quality High current density with stable pressure from the heat treated cast iron head supported by four heavy duty steel columns results in high penetration and excellent welding quality. Cooling is Vital in Performance The Inverter DC transformers, electrodes and secondary coils are water cooled. The diodes are continuously cooled by chiller*. A series of fans are built in to eliminate condensation and maintain system stability. * Chiller is provided as an option.
