The descent speed of the pressurizing head can be adjusted arbitrarily to alleviate the impact on the welded object during pressurization. Equipped with upward buffering adjustment function; Reducing mechanical impact improves the service life of the cylinder block and also reduces noise.

The direct pressure mechanism has good follow-up performance, and the guiding part is made of special materials with low friction. The electromagnetic valve is directly connected to the cylinder, accelerating the action response speed and improving the tapping speed.
