<DIV>Circuit Specialists (AZ) orders these models from the same Chinese mfg as everyone else -- and placed their name on them.</DIV>
<DIV> </DIV>
<DIV>The Aoyue and Madell Tech are the two best known "Chinese copies" of the Hakko (Japanese) designs.</DIV>
<DIV> </DIV>
<DIV>Aoyue</DIV>

<DIV>Aoyue use to have a direct copy of the Hakko 936, but they changed the case style and use a different conector (microphone connectors). Likely Hakko (a Japanese company) complained or took action</DIV>
<DIV> </DIV>
<DIV>Madell Tech QK-936A, they were using the correct Hakko style iron connector.</DIV>
<DIV><A href="http://www.madelltech.com/m3-8.html">http://www.madelltech.com/m3-8.html</A></DIV>
<DIV>Madell extensive line of inexpensive copies (spectrum analyzers, scopes, medical equipment, etc.)</DIV>

<DIV> </DIV>
<DIV>I have been told by other users -- that the true Hakko ceramic heater (made in Japan) is far superior to the heaters being produced in China. Some owners of the Aoyue desoldering station complained that the vacuum pump/motor assembly used by Aoyue were inferior, noisy and not of the same quality as Hakko models.</DIV>

<DIV>Solomon, Sorny Roong Industrial Co.,Ltd. is a well known Taiwanese company that has been producing OEM soldering units since the late 1970s. Circuit Specialists, MCM/Tenma and a number of other US comppanies sell these products. Replacement heaters are almost impossible to get in USA and you have to buy a new iron instead (if you can get one). The variety and seelction of soldering tips is limited -- with some models.</DIV>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN 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>
