1000Hz Medium Frequency DC Copper Spot Welding Machine For Copper Plate Welding 90KVA

• Frequency and Power Source:

  • Operates at a frequency of 1000Hz, which is considered medium frequency for welding applications.
  • Typically powered by a direct current (DC) source, ensuring stable and controlled electrical characteristics during the welding process.

• Transformer and Rectifier:

  • Includes a high-frequency transformer designed to step up the voltage to the required level for welding copper plates.
  • Rectification circuitry converts AC (alternating current) to DC, ensuring a smooth and continuous current flow necessary for precision welding.

• Control Systems:

  • Advanced control systems for precise adjustment of welding parameters such as current, voltage, pulse duration, and frequency.
  • Digital interfaces or control panels allow operators to set parameters according to the thickness and type of copper plates being welded.

• Welding Head and Electrodes:

  • Features a specialized welding head designed to accommodate the size and shape of copper plates, ensuring optimal contact and heat distribution.
  • Electrodes are typically made of materials that can withstand high temperatures and provide good electrical conductivity, crucial for effective welding.

• Cooling System:

  • Incorporates an efficient cooling system to maintain operational temperatures within safe limits, especially important during prolonged or intensive welding operations.

1. Energy-saving: The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss. And the grid power demand is low, only 2/3 of the AC resistance welding machine; the welding time is short and the electrode life is long.
2. Accuracy Control : The inverter frequency reaches above 1000Hz, and the welding current control ability and control accuracy are 20 times higher than those of AC welding machines.
3. Great quality : The current waveform is straight, the size of the nugget is stable, the spatter is less, and the surface quality of the solder
joint is good.
4. Easy Operation: Multiple sets of welding specifications can be stored and called with one key, real-time display of welding current and time, monitoring and alarm functions of welding pressure, cold water flow, and welding current.
