Hakko 700C help - UK Vintage Radio Repair and Restoration Discussion Forum

Hi all. I have a Hakko 700C thats stopped sensing temp. It fell off a shelf, broke the element in the soldering iron. I swapped the element out and now it's not sensing temp.

Any ideas would be great thanks.

The instructions say that you should be able to measure around 43 to 58 ohms for the sensor between pins 1 & 2 of the soldering iron connector (from page 11 of this manual);

Is it just the iron that fell off the shelf or the whole station?

Thanks David , it was actually the whole ****** shelf that fell off that wall ..haha .. However , I have got it sorted now . Its was a duff element , luckily I bought three . The second one I put in worked ok . They are cheap Chinese elements , I`ve been using them for years now and thats the first one I`ve had that has given me any problems so it`s not so bad. Was just the falling shelf incident that put my mind on a "oh no" path.lol .

This is by far the best Iron I`ve had , I`ve had it about 12 years now and its been brilliant . So I would be devastated if it was to break . You know what its like trying to solder with a different iron , just feels wrong doesnt it .lol .

Many thanks for the manual ! appreciated .
