I live in Turkey and the Fronius service in Turkey wants to replace the cables I replaced. I think the wire burning characteristics in the RCU panel are missing. It can create a new characteristic and weld well for 1 day, but when I run it the next day or after resting for 1-2 hours, it cannot do pulsed welding again. Does a place need to be heated for pulsed welding? No matter what I did, it didn't work. Has anyone experienced something like this? Is there a filter that I need to clean or a unit that needs to be heated?
