Acetylene! What am I missing here?

[Alexander]

My new acetylene tank has a male thread. My old fuel regulator also has a male thread. Is there some sort of adapter I need to buy now? Please view the picture and let me know what I need to make this work.

The valve on your tank should be a CGA510 female. Looks like you have the CGA510 male on your regulator and your tank. I would talk to someone like OXYPRO to see if there is an adapter or if you need to change your valve.

This is what i have on my tank/regulator


You can just make out the valve/connector type if you zoom in.

 

[DPittman]

Yes your missing the adapter ...here's what it looks like on mine.

Where can I buy the adapter?

 

[RobinHood]

Try OXYPRO

Ugh. Oxypro. Prepare to pay and pay. Last time I called them they said a 135cu argon fill was $169 but today I can do it for $139. Jerks. $65 at kms. And that’s high. Both locations now suck. The other oxypro location charged me $35 for a spool 11lb of 0.35 mig wire. It’s $22 at kms right now.
Look online. Know your prices if you have to go there.

 

[RobinHood]

Measure the threads and make one, if prices at the shops are too high.

Alex where did you get your acetylene tank? Is it new?

 

[Alexander]

changing the valve is not an option because the tank is full and i bough this at KMS. They don't refill acetylene tanks they just exchange your old tank for a new one. this worked in my favour because my old tank was expired anyways. I'll buy the adapter the idea of machining a one off part with left hand internal threads and a special mating surface makes me cringe.

 

[Janger]

What did the trade in cost?

 

[Alexander]

I don't Rember I think maybe $100. They did not seem to mind that the tank was a lease from somewhere. They said if it is the same size we will take it. Now I have the exchange program cylinder. I'll go back next time I need a fill up. They did make me get my oxygen tank certified because they just refill that tank at KMS.

 

[PeterT]

Do you guys use KMS for (less expensive) TIG gas/tanks too?

 

[Alexander]

Sorry I don't have any other welding gas tanks. And I don't TIG weld

 

[Janger]

Yes I buy gas there. Argon. C25. The tanks seem a little pricey but I don’t know where else to go to spend less. There’s another thread on this. Renting at $10/month is the same as buying after 27 months. For a 110cu ft tank $280.

Here is the price list for cylinder purchasing and filling at KMS

Hi Alexander,

Can you post a photo of the front of the valve? I may know what CGA fitting it is that you need, but will need to check with my purchaser at work to source them.

Regards,

KMS had the part in stock so I no longer need one thanks though.
