Could someone provide a clear description of the proper way to break in the tips for the AiXun 3B. Instructions online (including AiXun website) focus primarily on features and basic operation but fail to either address microsoldering units or microsoldering unit tip break in. For example, Weller suggests a break in tinning temperature of 500 degrees. (Interestingly they do not mention F or C.) If C, obviously not applicable to AiXun with a top temp of 400 degrees C.

Thanks in advance!
