1. Support breakpoint startup, support automatic startup and manual startup mode conversion. 2. Simple programming, using motion controller, support array and non-array battery pack for fast programming. 3. Welding needle replacement forecasting and warning, self-contained welding needle processing compensation function, welding needle adopts water cooling cycle, effectively reducing welding pin loss. 4. With a welding current monitoring system, the welding current can be monitored in real time, effectively solving the phenomenon of virtual welding and false welding.
