Oxygen percentage needed for minor?

[Hotglass28]

Hi there all, can someone tell me if I can use a air compressor on a minor or is the oxygen content not high enough.

What is the percentage of oxygen that is produced from the oxycons?  Just out of interest.

I was talking to a welding friend and he reckons that a belt driven compressor will be cheaper and might do the job. (has plenty of PSI)

Thanks in advance if you got any ideas.

Compressors will be noisy though.

a good oxycon will produce about 70-80% oxygen... the torches are designed to work at a certain pressure level and flowrate to ensure the correct mix at the torch face - i have no idea what a minor would be like on compressed air, anyone feel like having a (careful) go?...

I know the little Japanese torches use a compressor, and they're definitely not as hot.

Ah, the percentage thing has answered my question.

The belt driven compressors are silent, well the one I'm on about anyway.

I think I will go for an oxycon or that other make I cant think of the name. 

What are the differences if any. warranty? easily fixed? good to be outdoors in the shed?

If anyone can help and give me an idea on which one I'd be thankfull.  I'm in the dark on this one.

Cheers
