Medium Frequency Inverter Resistance Spot Welding Machine for Metal

Product Description

Medium frequency inverter resistance spot welding machine is an advanced welding equipment. Widely used, welding transformers is small volume while high output energy. The integrated transformer quick welding tongs used in the automotive industry are particularly advantageous. And its superior performance is due to the increase in welding transformer frequency from 50/60Hz to 1000Hz, greatly reducing the weight of the iron core l. In addition, the rectifier diode in the secondary circuit of the transformer can converts electrical energy into DC power for welding use.
Features 1.The welding current is direct current, and when there is induction and magnetic material in the secondary winding, it will not affect the welding.
2.To balance the load of the power supply equipment, the medium frequency inverter point projection welding machine adopts a three-phase power supply with stronger adaptability to the fluctuations and voltage drops of the power grid.
3.More precise and rapid current control; Compared with power frequency systems, it can analyze parameters more accurately.
4.Medium frequency can adjust welding current 20 times faster than traditional techniques.
5.Welding reduces operating costs, including saving energy at each welding point and shortening the welding cycle.
6.Energy saving: Especially suitable for welding thick workpieces and highly conductive metals such as aluminum and all galvanized steel plates.
