I am getting LECO-067 Cap balance error, LECO-050 Cap A under voltage, LECO- 053 Cap B over voltage and LECO-055 Soft start failed, along with a loud popping sound when I tried to run the first weld with a robot. This robot has been unused for a few days but probably not more than a week, that amount of downtime has never been an issue before. Prior to that the robot ran flawlessly for at least a year so these errors are a big surprise.
Is the problem located within the weld equipment? I also got an ARC-008 Power supply fault error.
If it's in the controller what exactly am I looking for? I read the manual entries for these errors but they list an extensive list of possibilities and Im hoping to narrow it down. Going to start by checking 3 phase input and the PSU board.
This is a 120iB arcmate robot and an RJ3iB controller.
