Testing the torch with Brown's Gas allowed us to cut and weld cast iron (with oxygen added), vaporize tungsten and weld copper; also did brazing on iron. Adding gasoline as a modifier (1/2 quart) allowed us to weld iron, but only when we added oxygen to the flame.

We used the same torch tips and duplicated all the above feats with normal oxy./acet. Neither torch was able to weld stainless steel, aluminum or weld different metals together. The Brown's Gas torch did cut thick steel faster and cleaner than the oxy./acet. torch.

TESTING THE BN 200

These poor people bought this tiny electrolyzer at $2500 from Yull Brown himself (twice listed retail value). We took it out of the box (cut the seals ourselves) and discovered that it had been used (hydroxide spills and rust) and that it had no power cord.

We went to town and bought the components to make a power cord (12 gauge all weather stranded wire, a 240 VAC plug to fit the outlet we are using for the BN 1000E and a heavy duty "computer" cord with female plug (that being the power outlet for the BN 200).

I wired the cord (soldered all connections) and it looked and worked great. I put lye electrolyte @ 5:1 in the electrolyzer and turned it on. Nothing happened; well, OK, the power light came on.

Quick testing shows that the electronics are not turning on the electronic switch to allow the amperage to go through the electrolyzer. I think the electronic switch is good, but some other parameter (like malfunctioning pressure transducer) is causing the problem. Don't have time to fix it at this time; though the electronics seemed simple enough and could be reverse engineered.

Testing Conclusion:
The Brown's Gas BN 1000E makes the exact same quality gas (about 130%) as our current electrolyzer design, but our design takes almost exactly 1/3 LESS electricity to make the same volume of gas.

Operation of the BN 1000E is simple enough, once you know how to do it. In my opinion, the instruction manual and technical support from Yull Brown are not adequate to assure safe operation for a novice user (this includes someone knowledgeable as myself). This report will assist users of the BN 1000E to operate the machine safer. My own electrolyzer designs are fully documented and we give enthusiastic technical support to anyone using ANY (but particularly ours) electrolyzer.

The BN 1000E is quite presentable, looks good. And I'd consider it well designed, just not designed as well as it could be. I'd suggest several changes to make it safer and easier to use, but then we'd end up with my design. (check out the ER 1150 Water Torch)

The BN 1000E seems to suffer from a "China syndrome" of quality control. We found several problems, particularly in the electronics that could be traced directly to inadequate quality control. In short, the machine barely functioned, crippled by faulty (and complicated) electronics; for which there are no wiring schematic or technicians on this side of the Pacific.

The BN 1000E is made of mild iron, and already shows rust both inside and out. Personally I don't expect long life spans for these (expensive) machines. It will be particularly important to make sure the backfire arrester has adequate water in older machines, because the rust will eventually cause the electrolyzer to weaken and it will not be able to contain a backfire.

The BN 200 suffers from the "China syndrome" too. In my opinion, the torch tips are also too large a diameter for the electrolyzer capabilities. Backfires assured.
