Hello, my question would be how often you clean the pot? The second picture with the particles looks for me like burned flux etc. When you took out a large quantity of solder dross, I think that big amount of it was released into system.

Clean the solder with the perforated spoon. Take out the solder from the pot. Clean the walls, heaters and equipment.

Best regards

That definitely looks like flux. Have the settings been altered? Bottle pressure? Line Speeds? Durations?

Possible fluxer failure?
