Hello folks. I have an interesting situation that none of the welding shops around me can answer.
I’ve added a Tig welder to my current Mig table setup. All was well until i realized That the space for the Argon tank is about a 1/4” too short. I’m using the ball bearing type regulator. So to fix this i found a 24” high pressure hose (3600 psi) Rated for Argon, CO2 etc. that i can run between the cylinder and the regulator safely under the table top. The tank when fresh filled is usually no more than 2000 psi.
I have separated the brass 1/4” npt from the cylinder side of the regulator and will insert the HP hose between that and the inlet side of the regulator. Just want know if its safe or any other foreseeable problems before i find out the hard way.
Sorry for the long post.
I think I would second Oscars input.
I'm not an over the top safety nanny, but I also don't feel the need to take any chance that I really don't have to. If I have a safer approach, I will default to that.
I'm not 100% sure that I am picturing the problem you are trying to solve, but if there is a way to do it by working with the LP outlet side of the regulator that would be far preferable. Should also be easier and less costly.
All that said, there are of course safe ways to do what you are proposing, you would hardly be the first person to do so. Just be 100% sure that you are not overlooking any details. Sometimes small seemingly insignificant things can come into play at high pressures. If I were doing this I would honestly be asking advice from a place that deals with such things, like a gas supplier. For stuff that I don't fully understand and that can get me hurt, I take any information gathered online with a pretty large grain of salt.

Safety aside, it will waste gas if you fill that HP line to tank pressure and then it ends up getting purged or bleeds out of the line at any point overnight. Might add up over time. Personally, I only take LP away from the tanks.
