I visit this site most everyday. I post rarely. I know this has been discussed but I forgot which is up and which is down.

I need to make a low mig cart to slide into a small space. Can argon/C02 be laid flat and be used while it is in the flat position. I know acetelene must be vertical but I don't know about C02/Argon. Are all Argon regulators created equal - in that they can be used in any orientation?

Thanks for your thoughts.
