Wiki page on Immersion heater thermostat?

[Jamesrl]

Seems I've overthunk and and over complicated things (again).

Not really, remember LOTS of peeps read these posts so a  cautious approach is best, ask the question.

New thermostats are set at a relatively low temperature, a blob of silicon on most, I wind the stat up to max remove the cap and knob, spin the knob back 90deg and rebuild.

Do they not have a high temperature trip now-a-days?

Yes they do, that's why it's best NOT to remove the thermostat form an immersion.

If any or all things fail the power is cut at the 95C mark.

Just done it. Basically, there are two terminals in the box on the end of the thermostat. The live goes into one terminal. There is a set of points. The one side of the points is on a bi-metal strip. The adjuster controls the pressure on the bi-metal strip, and thus the temperature before it cuts out. As far as I can tell, undoing the adjuster, and releasing the pressure on the strip will give the highest temp.

The other terminal is power out to the one side of the element, there is another set of points on a bi-metal strip. These are not adjustable, so I guess that is the max temp cutout.

Now the Mig has run out of gas. Grrrrr.........

I got loooooaaaaaaads o'gas thank you.

Is it too late to get photos of what you've done?  We could put a wiki page together with a strong rider I guess.

It'll be interesting to know at what temperature the additional cut out operates.  If you can ascertain that it would be good info for the page.

Similarly if you have any info or photos, Jim we could include those.

I can take some photos of the inside of the stat. No trouble.

I guess once its up and running, I might be able to tell where the cutout operates. No problem.

Depending on the make of stat the cutout could be between 85 and 95. I can get my reactor up to 95 without a problem.

It's woth adding that not all immersion heaters have the cutout built into the stat,
some have a seperet cutout mounted on the heater backplate.

Roger that. I'm hoping to write a wiki article. Remind me to include that. Sometime around Christmas..............
