1. direct-pressure mechanism, emergency performance, high welding speed, orientation using the special material with small, solenoid valve and cylinder is directly connected to speed up reaction rates, increasing RBIs speed

2. has any speed of high-speed back-pressure, adjustable back-pressure head drop speed, easing the impact on the object to be welded under pressure.

3. main circuit using high power thyristor (SCR), contactless switch, the output current is strong, stable and reliable

4. water-forced cooling and circulating cooling water, and avoid the waste of water, dramatically reduce the amount of water.
