TBVECHI 200W Electrolysis Water Machine Hydrogen and Oxygen Flame Generator Water Welder AC 100-240V

Make sure you follow the directions exactly. If yours comes without instructions contact the seller and ask for them. After following the PDF they sent me it worked flawlessly. DO NOT USE all of the sodium hydroxide they send you in one go. Mix 3g sodium hydroxide with 600 ml of water. Fill each container ONY 2/3 full, not completely full. Do a water test for leaks before you put your sodium hydroxide solution in and make sure everything is tight, including the wires. If the power supply turns off, it could be because you used too high a concentration of sodium hydroxide.

Got this one today, excited, put it together. Followed the instruction. One thing noted though, the instruction was not accurate. You should only pore the sodium hydroxide solution into the eletrolysis drum, not into the water tank. Therefore you don't need 600ml of solution. Maybe only 250ml or 300ml, so you don't need 3g of sodium hydroxide, maybe 1.5g. You should only add water to the water tank, cause this water will never get into the eletrolysis drum, and you want the water tank's water to filter out any potential foam coming out of the drum. But nonetheless, the system works, it produces enough H2 and O2 to light up the torch. However, I'm not sure if it's my system or a design issue, the eletrolysis drum is getting hot very quickly, probably less than 10 minutes, the solution in the drum started bobbling, and the acylic case for the durm was too hot to touch. Plus when the temperature rises above 80c, the chemical will have some corrossion effect on the stainless steel and copper. Anyone else has this problem ? Something more I want to say about this product, it's beautifully made, very good quality materials, functioned well with the exception that the power supply was wrong. I think it's over powering the reaction, cauing the solution to boil in a short time. The seller responded to my complain very quickly. Good service.

Received this product with the assumption that it was brand new and when I opened it, it was covered in chemical that burned your skin when you touch it. What the heck!!

Ultimately, I’m experimenting and ultimately want to make Hydrogen with solar. Although, this is HHO.

All parts were there, it went together easy, however, when i went to try it out nothing happend. Its turns out the power supply was non functional. I was not able to bring the power supply to life so. On to strp 2, checking into what's next.

Works good. Be careful with minimal use the inverter will stop and the flame will travel up the hose and blow off. I’ve put a backup power source to it in order to give me time to shut it down.

be aware potassium/sodium hydroxide electrolyte mixture is capable of chemical burn to hands wear gloves (in response to previous review)
