Hello friends at Adafruit!
I am writing about a problem I'm having with my new Hakko FX-888 (936 upgrade) (FX-888)
It worked beautifully out of the box...I usually set it 350-375 and it
did a beautiful job, really nice. In the last week though I'm guessing
it's not getting up to temp, the solder is not flowing properly. I
don't have a tip measurement device, so I'm at a loss as to how to
recalibrate it, if that's the problem. I'm noticing that the light
cycles on/off to hold temperature while the iron is in the stand ...
the light comes on for maybe a 1/4 second, then it's off, and the
cycle repeats every second or second-and-a-half. Is that normal?
The iron actually hasn't gotten more than 2 or 3 hours ON time since I
got it since I've been off on soft projects...but I went back to the
bench earlier this week and noticed the iron was behaving differently.
I checked the tip of course, and it's clean and shiny.
Any help you can offer?
