If you are in the US, I know that most cities and town that
provide natural gas usually provide it at about 2lbs of pressure
out going so that should be enough for a small shop set up for
soldering and casting.
This isn’t always true - in many places typical gas pressure is 1/4
psi (also refered to as 7" Water Column, 28" Water Column = 1 psi),
which is not enough to flow through a flashback arrestor so when you
use a flashback arrestor it will block gas flow. Depending on the
manufacturer it takes between 1 to 3 psi to open the flashback
arrestor valve and get a good gas flow.
Natural gas appliances use 1/4 psi gas so if you are in a
residential area then this is most likely your gas pressure. If you
are in a commercial area you may be able to get higher pressure
service but you might need to put regulators on the hot water heater,
space heaters and other equipment that uses natural gas.
It was more than adequate for their needs but at a cost of $2000.00
for the generator, it better be!
Depending on your gas requirements we have Torch Boosters priced
much lower than that! Please visit our website -
