DDIS-GT
GT Model
Single/ Dual Cross Bar Grating Welding
Appliaction | Industrial Construction Industry
- Grating
Specification:
- Energy Efficient
Three Phase Inverter DC Output Current Solution
Three phase balanced input with constant DC output can save 70% of energy consumption compared to standard Single Phase AC machines! Lowly 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.
- Higher Return on Investment
Lower Energy Cost and Efficient Production
With the benefit of energy cost saving up to 70%, it could save up to US$20,000 in annual energy cost compared to AC machines. It is with lower connected load.
- High Production Efficiency
Preload System
Operators can load the bearing bars onto the preload system for automatic feeding into the welding station without stopping the machine. Safety and efficiency are both reinforced.
- Manpower Saved & Safety Increased
Cross Bar Automatic Loading System
The pneumatic automatic loader feeds and positions two twisted bars onto the welding position before welding in an accurate manner.
- Good Welding Quality
High current density with rigid pressure come from the heat-treated cast iron head, which is supported by four heavy duty steel columns results in high penetration and excellent welding quality.
- Excellent Cooling
The inverter DC transformers, electrodes, and secondary coils are water cooled. The diodes are cooled by chiller* in a continuous manner. A series of built-in fans eliminate condensation and maintain system stability.
* Chiller is an optional equipment.
