I was told at breakfast this morning with my buddies that there will be no more acetylene produced or at least it will soar to ridiculous prices (ie: gasoline)

any welding gas-supply folks on here that can shed some light?

I work for a welding supplier, if you haven't swapped your cylinder out recently, you may want to do so. There are other suppliers in the area that are already denying over the counter accounts to help keep their stock high for their larger customers.

The latest update is that the calcium carbide plant will start importing, repackaging and distributing soon, but does not plan to be up and running producing their own product for about a year!

If you use a lot of acetylene for cutting and heating, you may want to looking into switching to propylene (tips hoses and possibly regulators need to be switched out) I have heard rumors (although our supplier has not been drastic) of 50% increase in costs and 50% reduction in availability over your last years purchases. It will most likely get worse in the coming months.

I have a full tank in the garage, I always make the joke to the kid that it's the bomb that will destroy the house in a fire. Maybe I should sell it when prices get high and switch to propane/oxy. Can I keep my torches and regs if I switch to propane (victor mid level setup)? I know the hoses have to be rated for propane.

Do you do any welding or just heating and cutting?

Any alternate fuel requires a "T" grade hose. Most likely your hose is a "R" grade which is for acetylene gas only.If you aren't certain or can no longer read it on the hose, I would suggest replacing it.

You also have to switch out your cutting and heating tips to match the alt fuel that you are using.

The regulator should be a CGA 510 (standard commercial acetylene) and should most likely be the same on the propane, but I would double check with your supplier to confirm it. There are adapters available from companies such as Western Enterprises, if needed if they use a CGA 300 for example in place of the 510.

As long as the delivery pressure for your alternate fuel does not exceed the 15 psi of your ACE reg, that should be all you need. There are charts available listing the required pressures for the heating and cutting tips.

If you switch back from alternate fuel to Acetylene, you will want to purge your regulator with N2 or send it in to have it cleaned professionally. There is a chance the residual alt fuel in the reg could react with the ace.

Hope that helps. I would suggest talking to you gas supplier, they should be able to assist you as well with the best options for you application.

^^ thanks for the info, I do weld with the setup occasionally too, and have quite a bit of dough invested in all the welding, rosebud, and cutting tips. I'll just use the acety sparingly I suppose.

I use propane interchangeably with acetylene and have for 30 years. The instruction sheet that came with my Sears kit stated that they could be used interchangeably.

Many of my neighbors do the same.

I'm gonna get my tanks filled tomorrow while there's still time-if it's not too late already!

Any idea how long this is going to last? Was the plant a total lose or is it only going to take a few months to get back into some kind of production?

Here's the latest news story I was able to find:

http://www.fox41.com/story/14432197...perates-differently-following-fatal-explosion

LOUISVILLE, KY. (WDRB Fox 41) -- Carbide Industries employees returned to work this week operating the plant in a much different way, following a fatal plant explosion.

The sign in front of the company reads "Phoenix Rising." With it is a note in memory of Louie Medina and Steve Nichols, the workers who died in the March 21 blast.

"Three weeks ago was pretty devastating," says plant manager John Gant. But he says the sign speaks to the company's current state -- acknowledging the loss while looking to move forward.

Gant says 130 workers returned to work focused on transitioning the plant from carbide production to carbide shipping. The company's bringing in the product from countries such as Mexico, China, and Sweden to fill its orders.

Gant says, "In June we'll have 100 percent of our customers' requirements coming in drums, and it takes a lot of work to open them up, empty them, put them in the proper containers for our customers and ship them."

Gant says it is not a profitable solution -- just a way to get by. The furnace fire burned for a week and reduced the building to a charred shell. "Our target is April 2012 to start it up."

On Tuesday Gant shared how timing is key. A rebuild requires new permits and could cost tens of millions of dollars. He says city leaders are aiding in the process: "Economic incentives and I got a call into Greater Louisville, Inc."

Yet nothing moves forward until they find a cause to the explosion. The Chemical Safety Board, OSHA, and arson investigators have all combed the scene but haven't released a report.

Fox 41 News has been told Carbide investigators will be on the ground in the next two weeks and the company has already ruled out arson and employee error.

Gant says, "We have educated guesses, but we have to know exactly what happened. That's why we're bringing the external guys in. To make calcium carbide is a very simple process -- coke, lime and electricity in the furnace. We've been making it here since 1941 and never had an incident like this and when we start it back up the process will be the same, so we have to know what happened to prevent it from happening again."

The company did make some cuts, releasing six workers, since they're already overstaffed for their current demand. Those workers started on the day of the explosion.
