Hi Peter, If you have the L&R bottles of potassium hydroxide take a
gallon of distilled water and pour out a couple of cups of water.
Then add the entire contents of 2 bottles from L&R. Close the
distilled water bottle and shake to mix the chemical. Fill up your
tank to the appropriate level. If the tank is not full with the
gallon then just add distilled water to top it off the rest of the
way.
Most torches won't have a tank big enough to hold more than a
gallon.
This should be all you need to get it working.
If you have another type of potassium hydroxide I am not sure the
amount you would need per gallon of water. It would depend on what
grade of chemical you have.
You could just add about 8 oz. to a gallon and try it. If it works
then you can use that if not add another 8 oz. It should work at that
concentration.
Before adding any to your machine you should be sure your machine
works properly first. These machines are bombs and can explode if not
in proper operating condition.
Hope this helps.
