Hi there,

looking to set up pressurized co2 in my up coming project just wanted to clarify what is need

Gas Bottle (can any gas bottle(new) do or does it have to be specifically for co2)
Gauge/tap with solenoid something like this http://cgi.ebay.com.au/ws/eBayISAPI...m=250281871256&ssPageName=STRK:MEWA:IT&ih=015

and optional a controller something like this http://cgi.ebay.com.au/ws/eBayISAPI...m=150282312792&ssPageName=STRK:MEWA:IT&ih=005 or like this one http://cgi.ebay.com.au/ws/eBayISAPI...m=250281937252&ssPageName=STRK:MEWA:IT&ih=015

am I on the right track?
is there anything else?

Regards Darren

Here is a good link thst shows each component & explanations... http://www.njagc.net/articles/co2.htm

The regulator you link to is high priced. I got one shipped for around $80 which I purchased from Aqua Buys.

All pressurized gas bottles use specific, non-interchangeable outlet fittings. This is to prevent inadventently putting the wrong gas in the bottle - CO2 in an oxygen bottle, for example. So, you do need a CO2 bottle for CO2. If you had the right equipment you could switch a different gas bottle to a CO2 bottle by replacing the valve/fitting on top, but it is much better to just get the right bottle to start with.

hoppy it depends on the size of the bottle when your welding you don't ever change the regulator just the bottle/bottles depending on your setup and in welding you use argon oxygen and co2 for the different types of metals


edit but i should point out that all the bottles are made with different fillers and metals depending on the gas requirements

There are standard regulators made for use with any of argon, argon/CO2, and CO2, all of which are inert gases, and all of which would be a problem if you mixed them up with oxygen. I don't believe oxygen will ever be in a bottle where you could use the same regulator as for CO2. That would be a disaster waiting to happen.
