Just picked up a brand new oxy-acetylene setup on thursday (that wasn't cheap!). Got it all hooked up, went to purge the lines, and the acetylene is leaking at the tank connection. (the big brass fitting with the beveled face on the inside) I've tried cleaning it out and retightening the valve a bunch of times but it's still hissing. I have no experience with these gas cylinders, any little tricks? or do i need to take it back to the welding shop and exchange it for a new one? thanks. |

They either work or they don't. Get it replaced. |

Yeah, get it replaced. Remember to NEVER use any sort of oil or other substance to help it seal either. Those things have to work dry. |

It's possible that in handling, the ball end on the gauge set has a little ding in it rather than the tank being defective. Inspect it closely with a magnifying glass. Also, sometimes they just don't seat right when you first put them together. Loosen the nut, wiggle the gauge's to be sure they are square, and retighten. |

Put a bit of effort into tightening it. I don't know the torque spec, but I have had the same situation. Loosen it, turn it to kind of bed it, then tighten it pretty damn tight. Best leak tester is soapy water. If you smell it or hear it it is a serious issue. |

When you say new rig, I assume you mean torch set, not tanks. It is very common for the tank valves to get dinged up and fail to seal. If that is the case, take the tank back for exchange. Speaking of tanks, there are rental/lease tanks that are owned by the supplier, new retail tanks sold by some suppliers and tanks that are stamped "CO" (customer owned). When you get tanks, outright buy them only stamped as "CO". Those are the ones that can be swapped out virtually anywhere. Rental/lease tanks have an ongoing cost, and in some places new retail tanks cannot be exchanged depending on who you deal with. For the home work shop use, one good supplier that may be local (and open on Sunday, the most likely day to run out of gas) is Tractor Supply. They will exchange "CO" tanks. |

Fast, you're right, i got a new Smith torch kit, and i'll have to check the bottles to say if they're CO or not. I haven't seen a TSC since i moved out to Washington. I'm just glad they have Oreilly's out here! |
