Intermediate Frequency DC Seam Welding Machine

Product Features:

1. Energy Saving:
   Compared to low-frequency systems, medium-frequency spot welding machines reduce energy consumption. The same-weight transformer can output more power and is easily compatible with large automatic welding pliers. Suitable for welding thicker workpieces and metals with high conductivity, such as aluminum and galvanized steel. Smaller and lighter systems can accelerate movement and shorten work cycles, making them ideal for welding machines/automated machinery.
2. Reduced Parallel Secondary Circuits:
   In semi-automatic setups, a medium-frequency welding transformer can replace several low-frequency transformers, reducing the need for parallel secondary circuits.
3. Lower Production Costs:
   Reduces energy consumption by over 30%, thus lowering production costs.
4. Minimized Interference in Large Secondary Circuits:
   The welding current is direct current (DC), so it doesn’t affect the welding process when there are inductive or magnetic materials in the secondary windings.
5. Balanced Power Load for Supply Equipment:
   The medium-frequency inverter spot welding machine uses a three-phase power source and can store energy, leading to better load distribution.
6. Stronger Adaptability to Power Grid Fluctuations and Voltage Drops:
   A portion of the energy is stored by the inverter and supplied to the load, replacing direct supply from the power grid to the load.
7. More Accurate and Faster Current Control:
   Compared to low-frequency systems, medium-frequency systems can analyze parameters more accurately and provide better control of welding current.
8. Faster Response to Set Current:
   Medium-frequency systems can adjust welding current up to 20 times faster than traditional technologies.

Product Classification:

Medium-frequency seam welding can be classified into three types based on the roller rotation method:

• Continuous Seam Welding
• Intermittent Seam Welding
• Step Seam Welding
