Hey all,
I have a weller wesd51 that in the middle of heating just decided to stop working. Done as much research on it as I could but can't find a lot of info on specific station.
It turns on fine but one thing that's throwing me is if I turn it on a d unplug the pencil from the unit it reads 900 on the display, but as soon as I plug it back it it jumps to 240. I can adjust the dial and it goes to its normal 850 max reading, but soon as I do it just jumps back to the 240 reading and never heats up..
Maybe a sensor problem in the pencil?
Any ideas appreciated..
