Fascinated by hydrolysis apparatuses? Me too. Here’s a cool how-to that might convince you to make one! It’s a very simple and easy to build HHO torch using plumbing parts from the hardware store.
The entire build uses almost all standard readily available parts — except for the nozzle assembly. It’s an easy modification though, under the copper pipe endcap is a brass M6 nut that has been soldered in place – this allows you to switch out the MIG welding tips at any time.
[Peter] also shows off another useful tip that allows you to reduce the orifice size of the MIG welding tip – simply hammer a ball bearing into it. Seriously, check out the Instructable and see for yourself! This allows him to reduce the orifice size down to non-standard sizes which in turn allows him to increase the intensity of his HHO flame.
Now all you need is a source of HHO — but don’t worry, we’ve covered that before too!
