What to do if the ARCCAPTAIN Welding System LED display shows "EXX"?

If the ARCCAPTAIN Welding System's LED display shows "EXX", it could be due to a couple of reasons. First, check that the power cord is securely connected, as the issue might be a power input phase loss. If the problem continues, it is recommended to contact the company's after-sales department. Alternatively, the "EXX" error might indicate overheat protection, in which case the welder will automatically resume functioning once it has cooled down.
