1000Hz Medium Frequency DC Copper Spot Welding Machine For Copper Plate Welding 90KVA
1000Hz Medium Frequency DC Welding Machine for Copper Plate Welding
Description Of Precision Micro Spot Welder
Precision Spot Welder not only possesses the general features of capacitor discharge spot welding machine, but also possesses other performance features as follows
-
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.
Feature of of The Medium Frequency Spot Welding Machine
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.
