Product Details:

The mid-frequency inverter spot and projection welding machine is a high-efficiency DC resistance welding equipment based on mid-frequency (typically around 1000 Hz) inverter technology. It converts AC power into high-frequency DC output, achieving smooth current flow, precise control, and high welding efficiency. Compared to traditional AC welders, mid-frequency welders offer higher thermal efficiency, more stable weld quality, and lower energy consumption, making them the mainstream equipment for modern metal welding production.

These models cover a wide range of power requirements, from medium to low power to large power, catering to various welding scenarios.
They are suitable for spot and projection welding of various metal materials such as steel, galvanized steel, stainless steel, aluminum, and copper. Common applications include automobile manufacturing, hardware components, new energy equipment, electrical hardware, metal enclosures, and more.
