00:00Special pulse-spot welders are required for welding batteries
00:02because it releases energy in a very short time
00:04which will not damage the battery
00:05Non-pulse-spot welders have a long discharge time
00:07which easily generates high temperatures
00:09which can increase the internal resistance of the battery
00:10and shorten lifespan
00:12which cannot meet the safety and performance
00:13safety and performance requirements
00:15therefore it cannot be used for battery welding
