So my co2 reulator only goes until 130psi, and im looking for 200psi. so does anyone kmnow of a cheap CO2 flow regulator that only regulates flow and not pressure?? i have a bulk tank btw.

thx. n hapy holidays

Um, you could use a MIG regulator. My Licoln dowstairs will go up pretty high on the CFH, though I couldn't tell you what pressure it is. Ok, I just priced a cheap yet decent Hobart reg which is $66 bucks (your prices may vary) and it goes to 50 CFH which calcs to .83 CFM, not much but this is a small reg. Found it on Northern Tool, great store.

Edit: Co2 is sometimes used as a MIG gas, some guys swear buy it, many stores have adapters for regulators on the cheap. However only inert gas regulators can be used with other inert gas tanks. Just like fuel regs stay with fuel. With an argon regulator you will need a coupler since both Co2 tank and reg are male threads (last time I check a Co2 tank in the tank house at school it was, I think).

different threads are on different gas bottles. not sure bout co2 and mig gases but check first.

what are MIG gasses?

shelding gases used in welding. the big blue or in the us i think its brown bottle. mig stands for Metal Inert Gas. (welding)

edit: the brown bottle would be helium

the mig bottles have different threads.

MIG gasses are generally a mix of of co2 and argon, its like a 85% co2 and 15% argon I think. And they don't have to come in a specific colored bottle.
I'm not sure about the flow regulator though

in aus they come colour coded. and it 15% co2 and 85% argon depending on use. does anyone have one to see if it fits

I have a tank of C25 in my garage, the typical mix is co2 25% argon 75%. Those have a lefthand threaded female valve. Regardless of what's in the tank or what color it is there are really only 4 different threads, you can get adapters for all of them at a welding supply or welding gas store. Also its not really a "MIG" gas its just an inert gas used in welding. CO2, Argon, C25, and others are used. Main thing is you can use an argon flow regulator to regulate all of these gasses. I've never heard of helium being used in welding but the regulators are all the same. I know helium is used in CO2 laser systems to kick start the lasing process.

Brown is usually argon 100%. A MIG tank, is 75% argon and 25% co2 and is a brown will silver top.

Not trying to be rude-I have quite a few certifications in AWS (american welders society) in MIG,TIG, Stick/Arc and oxy-acytelene. All starting with d1.1 and up.
Just want to make sure everyone knows Im a fairly reliable source about that.

Ah ok I thought i had my percentages mixed and wrong. Thats interesting, I did't know Australia color coded their bottles.

Im talking about usa.
