Product Description

Intermediate Frequency Inverter DC Spot Welder

The medium frequency inverter DC spot welder converts 50Hz AC to 1000Hz MF DC output, and the time resolution and control accuracy are higher than lF welding machine. lt output current is stable, thermal efficiency is high, output power is high, and welding quality is excellent. Compared with traditional frequency welding machines, this equipment is highly efficient and energy-saving, and is a technological innovation in the field of resistance welding.
This machine is suitable for metal materials such as aluminum and copper, as well as high-temperature enameled wire soft connection and induction coil welding, and is used in automobile manufacturing, new energy power batteries, hardware furniture and other fields.
