**Intermediate-Frequency Inverse DC Spot (Projection) Welding Machine** • The direct pressure mechanism offers excellent servo performance and fast welding speed. The guiding system uses special materials with low friction, while the electromagnetic valve and cylinder are directly connected to increase action speed, improve beating speed, and reduce air flow loss. • It has a long service life and operates quietly. The adjustable pressure speed function allows for flexible control of the upper and lower speed of the pressure head, reducing impact on the welds. The rising buffer function enables smooth adjustment of the ascending and buffering speed, minimizing mechanical stress and extending the life of the cylinder block, as well as reducing noise. • Designed for safety and ease of use, it features a high-performance gas circuit filter cup with a shield that prevents glass debris from splashing and protects against external impacts. The cups and shields are easy to handle and maintain. Intermediate-Frequency Inverse DC Spot (Projection) Welder
