style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Thanks for this very
useful information. Being a pack rat, I saved all the parts of my WCC100
soldering iron. I thought I might run across a used one or a source for
parts to fix mine one day, and so I did. I now plan to order a new heater,
sensor and board to fix mine up. It was a great iron and served me well
for several years. Since I had many tips for the model 100, when it
failed, I went ahead and bought a Weller WES51 so I could use the tips I already
had. Once I fix the WCC100 I will have two great irons with
interchangeable tips.</SPAN></FONT></P>
