Also how do you connect the hose to the natural gas line?

[TimiaGlass]

1/2" gas pipe to valve. Valve to copper fitting adapter. Then a copper tube fitting to the adapter with a few inches of copper tube. Then clamp the hose on the copper tubing. You can get the parts at any hardware store.

I also have natural gas in my house. How do you know the hose pressure without a regulator?

[TimiaGlass]

Natural gas pressure is going to be a few ounces. No regulator needed. You are counting on volume to supply enough gas for the flame. You will have enough volume for the 3-A for sure. Larger torches may be iffy.

hmm..from what i've read, u have to turn off gas first to prevent flashback, not oxygen. The oxygen passing through after turning off the gas will clear out the mixing chamber and cool the torch tip a little.. I have no experience tho'...

[TimiaGlass]

O2 off first is what I was taught. The Bethlehem Apparatus manual many of their torches state the following:

"To extinguish the flame you should always turn off the

oxygen before the gas. Do not over tighten the valves."

I suppose the best thing to do is consult the manual for your torch and do what it recommends.

It's fuel on first and off last. The theory is that if you let the fuel out of the lines first then there is room for oxy to back up into the fuel line and possibly cause flashback which might go back to the tank. If the fuel line is full of fuel then oxy can't get into the fuel line to cause combustion. This only applies to internal mix(premix) torches. surface mix lets the oxy right out and it can't get back in.
