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 when compared to 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 the 70% energy cost saving, it could save up to US$20,000 in energy cost per year compared with AC machine. low connected load requirement.

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 weld.

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 is built in to eliminate condensation and maintain system stability.
* Chiller is provided as an option.
