Smoke Machine Repair

SO much for attempting to gain the moral high ground!

...for this, and anything else your unsure of, I would get a tech to repair it and sign it off for insurance purposes. I'm confident when I can source parts and make the correct repair and have at minimum it pass PAT. But if you you are EVER unsure, get it don't by somebody qualified so that you are inline with you liability insurance and any other paper work that you COULD fall foul of by "bodging" or "hacking" away at and it be the downfall of your company. 

When blocks melt, you end up with a puddle of molten aluminium to contend with.

Aluminium is surprisingly "reactive", look what it does when powdered, mixed with "rust" and ignited with a magnesium ribbon for a fuse - called Thermite.

Used for "welding" train rails together in situ, when you haven't got a huge power supply for mig/stick/etc...

If the generic replacement block comes with a thermal trip in location, then it should trip before it melts. If you are placing thermal trip to generic block afterwards, you would need to test it to destruction to be sure...mewh.

I would be more concerned about the harmful effects of over heating glycols.
They become highly carcinogenic if over heated, long before you'll melt or burn anything down.
Its why cheap vapes can be potentially so harmful, if they haven't got adequate heat control.

We had a long discussion on photonlexicon about home made fluids and machines and some startling data was shared in terms of risk and temperature.
