Question on torch

**Gibwhiskey** · 04-02-2016, 11:18 AM

Can I use this older torch with an oxygen concentrator? It's labeled gas and air?

Any help would've appreciated. Thanks

If it's labeled gas and air I would not use oxygen, you'll melt it down in a heartbeat.

It looks like it has a venturi on the nozzle which furthers the argument that it is meant for air only, although I am by no means an expert, that's just my opinion.

No. I read somewhere else I shouldn't use oxygen, when it says air. I just wanted to get others opinions.
Thanks so much.

My National 3A says oxygen and air and it works with oxygen. Use flashback protectors and try it out.

Light it correctly so it dont pop and I bet it works fine.

Bad advice.

The national can be used with air or oxygen that is the way it's designed. Older burners used gas and air period. I've tried using oxygen with cross fires designed for air and gas the results. Well it started firing like a machine gun right before it spilt it's guts.

Bottom line don't give advice unless your 100% certain. If someone gets hurt following your advise it would be a shame.

it wont hurt to try, as much as you would like to think you know everything you dont know.

with the national it does not matter because they have tips that are for air, and tips that are for OXY. 100% you cannot use this torch with oxy. Plain and simple man, the tip is made for air. There is a large difference in port size and configuration and it will simple melt the tip off is use oxy, end of discussion, and end of pissing contest. Its all about the tip and this tip is for air and nothing else.
