The manual states nothing about this. Wasn't sure if they would coat the tip with anything from the manufacturer, as I had a hard time to tin the tip. I went with the Atten 938D, It was affordable and shipping was not outrageous. Why is it so many people refuse to ship to Canada. One guy quoted me 78.00 for I think one of the small Hakko stations. Got it shipped, a few extra tips and heating element for under 90.00 with 1 year warranty. From what I read it uses some Hakko parts and tips and reviews weren't all that bad. If it doesn't do the trick or perform for what I need it for, I guess I will have to splurge.
