Propane regulator question
I'm working with our local propane (and propane accessories guy to get a
100# propane tank for the studio. He has some regulators on hand and has asked specifically what sort of PSI lampworking uses for the propane end of the mix. Can someone help me with that? In the books or sites I've seen, they talk about one-stage and two-stage regulators but they never mention the PSI needs. He has the two-stage regulators, I believe. Also, he thought that a flashback arrester was just sort of a gimmick. He had actually never heard of the term and is going home at lunch to look at the site where I first saw them to find out what they are. What's everyone's opinion on this bit of info? Does he not know what he's talking about, is the terminology just odd or are they a gimmick? Thx, Giselle |

You should be able to just use a pancake regulator with most torches;
it's a cheap little doohickey and drops the pressure down to about what you need, which is, depending on your torch, 5-10 PSI. A two-stage regulator is going to be a very large and not entirely necessary expense; most people do fine with single-stage regulators at half the cost. Pancake regulators are a fraction of even that cost. I'm mildly alarmed that Mr. Propane & Propane Accessories doesn't know what a flashback arrestor is. :O! All it is, is essentially a backflow valve that prevents anything (FIRE) from flowing backward into the tank and causing an explosion. You might want to check your Yellow Pages for a welding supply shop in your area. Their torches are very similar and the way you set them up is virtually identical, so they will probably be many times more helpful. They'll have the right hoses, regulators, quick-connects, flashback arrestors, the works.

Giselle, the pressure you need is determined in large part by the
torch you have. What torch will you be using? Also, the propane tank will be outside the studio, yes?

Also, the propane tank will be outside the studio, yes? We're deciding. Since we operate the house on propane, there's a 300# tank between the house and the studio location. The "studio" will be a room sectioned off in a large, empty metal structure. The tank can be place anywhere at this point but are you asking if it will it be far away from open flame? Far enough. I'm chicken. But I am getting used to living around tanks of propane that can obliterate all life in a 1/2 mile area. |

All it is, is essentially a backflow valve that prevents anything (FIRE) from flowing backward into the tank and causing an explosion. Yep, he said that can't happen. No propane = no flame. The end. Honest to God, unless they call it something entirely different here in East Bubblebutt, Indiana, he did not know what I was talking about. I gave him the backwash scenerio and he said he did not think it could possibly occur. Their welding torches do not use it. You might want to check your Yellow Pages for a welding supply shop in your area. Their torches are very similar and the way you set them up is virtually identical, so they will probably be many times more helpful. They'll have the right hoses, regulators, quick-connects, flashback arrestors, the works. Nearest welding place is like 50 miles away. I was hoping to find something closer to home but I'll keep it in mind in case I need to go elsewhere. Thx, Giselle |

The Minor requires2-5PSI for propane and 5-10PSI for O2.

Pancake regulators don't typically offer enough pressure to allow a
flashback arrestor to work. The good news is that for a surface mix torch, an arrestor really isn't required. Tink Martin - Art Glass Check here for available work: http://blackswampglassworks.com/latest.htm |

We're deciding. Since we operate the house on propane, there's a 300#

But I am getting used to living around tanks of propane that can obliterate all life in a 1/2 mile area. sheesh -why get another propane tank at all then? All you need is a T line off your main house tank - contact a local plumber and have them come in and plumb a line to the "studio." Most professional glass studios I have been in have such plumbed gas. Your local plumber can set you up with a proper connection and the proper regulation (if required)for your needs. Please don't depend on the people you have been talking to at the propane place - they obviously do not know what they are talking about. Additionally, I believe that you can run a Nortel Minor off regular "house" pressure line....they only need a few pounds like 5 psi. regardless - you should NOT PUT the tank inside the studio!

Cheryl House pressure is 1/2 PSI according to the guy I've been talking to. In fact, he says an entire neighborhood can be powered by that. (Hey, I'm just repeating what he's telling me.) My kid is resisting the line from the main tank to the studio. Plumbers are hard to come by here and, in the end, I'm not sure that will be any cheaper than the extra tank but I will call around. Would the plumber set up the line to go over or under ground? (One of her main objections is seeing the line go between the tank and the studio.) Giselle |

Hi Giselle,
I set up a shed studio in my backyard last fall and I was asking the same questions. I don't use propane at all in my house, so I had a 100 lb tank installed for the shed to supply both the torch (minor burner) and the wall mounted heater. The tank is about 10 feet from the shed sitting on a concrete pad. Copper tubing runs underground to the corner of the shed where it goes into a 25psi regulator. The output of the 25psi reg is then split into 2 separate lines - one goes to another regulator that brings the pressure down to the 1/2psi for the heater; the other line goes to a single-stage propane regulator* (with gauges for tank and line pressure) that can be adjusted from 0 to 25psi. Both lines coming into the shed have their own shut-off valves, and there is a master shutoff at the tank. *I bought the torch, hoses and regulator from Arrowsprings Meredith Fragile Warrior Bees wrote: I'm working with our local propane (and propane accessories guy to get a 100# propane tank for the studio.
