Assemble a HHO Mini Torch from plumbing parts by petercd on October 7, 2013
Intro: Assemble a HHO Mini Torch from plumbing parts Using plumbing parts, consisting of some compression and some solder fittings with the addition of a ½" L.P. gas hosetail, its possible to make a very servicable HHO gas torch. The temps are very low and so solder fittings will work, they also serve to keep the weight down by reducing the number of heavy brass fittings needed. My cell produces 1 lpm so the standard mig tip will need to be made smaller and we will cover that mod later on.
Image Notes 1. this second pic was taken 5min later and still not hot enough to burn fingers.
Step 1: Parts and exploded view The standard 15mm plumbing fittings are... 1. 6 inches 15mm copper tube 1" section between stopend and elbow. 1 ¼ " section between the coupler and the ball valve.( length is 30mm but 32mm seats well) remaining approx 4" between the elbow and ball valve. 2. 15mm copper stopend. 3. 15mm copper 90 °elbow. 4. coupler FIxC 15mm x ½ " 5. ½ " BSP hosetail which is a standard LP gas fitting. 6. mini ball valve compression fittings on both ends. 7. mig welder tip either 0.8mm or 0.9mm which will be modified. 8. a brass nut M6x1.9 for the mig tip. The mig tip has a metric thread M6x1.0 mm, so you will need to drill and tap suitable material if you dont have a M6 brass nut at hand.

Step 2: The Torch Tip The tip is the most fiddly part of construction due to the need for swapable tips. The copper stopend is too thin to support threading for the mig tip, so a brass nut is needed that can be soldered on in the inside, in order to remove the tip. I used the earth pin from a 15A 3pin plug which I drilled and tapped for M6 thread. Another option is the brass contacts on the old carbon dry cells which would also need to be drilled and tapped. It’s easier to first drill and tap the copper stopend and brass nut seperately and then insert a SS bolt to line the parts up when soldering, this way the ss bolt can be easily removed afterwards once all the soldering is finished.
Don’t solder with the copper mig tip in place because you won’t be able to remove it again. I had heard mig welder tips can be made smaller by tapping a ball bearing on top. It seems odd that forcing a ball bearing down would make the hole smaller, but the copper cant spread outwards and has nowhere else to go so it constricts thereby reducing the orifice diameter which works well. The smallest mig tip is 0.6mm which was unobtainable, I have used both the 0.9mm and the 0.8mm and managed to get the hole size down to 0.45 mm which is the size of some stainless steel leader tooth proof fishing wire I use for replacing cheese slicer wire.

Step 3: Closing bits The body of these mini torches is usually filled with fine brass wool, which reduces the instances of flashback considerably, I have retained the i nsides from interferring in the ball valve with a bit of fine screen wrapped around a washer. I used a M6 washer which I then had to grind down to fit inside the copper pipe. Its very convenient to be able to shut off the gas at will without constant banging from flashbacks, however... Don’t forget to switch off power to the cell once you have shut the ball valve, failure to do so will cause pressure buildup which could lead to leaks, explosions and equipment damage .
