**Intermediate-Frequency Inverse DC Spot (Projection) Welding Machine**
• The direct pressure mechanism offers excellent servo performance and fast welding speed. The guiding part uses special materials with low friction, and the electromagnetic valve is directly connected to the cylinder, which increases the action speed, improves the beat speed, and reduces air flow loss.
• Long service life and low noise. With adjustable pressure speed, the rising and falling speed of the pressure head can be adjusted arbitrarily, reducing the impact on the welds. The rising buffer function allows for adjustable ascending and buffering speed, minimizing mechanical impact and extending the lifespan of the cylinder block, as well as reducing noise.
• Safe and user-friendly design: High-performance gas circuit filter cups with shields prevent glass shattering debris from splashing and protect against external impacts. The cups and shields are easy to handle and maintain.
