Co2 regulator setup

[Umar1808]

Guys I need some help setting up my co2 gas regulator. I will be welding 3mm mild steel but need to know what the flow should be at the gauge and the flow meter?

8lpm at the flow meter will be ample.

My CO2 set up is much the same as yours. So I set the gauge (rh one) to more that I need say 20 lpm and then use the control on the flow meter for the final output which should need to be between 10 to 15 lpm

Note when yo open the bottle tap your right hand gauge (bottle pressure) will only go up to 20 to 40 on outer ring. This is normal for CO2. If you are use to Ar+CO2 then the gauge would go up MUCH higher!!

15lpm?? Wow..

Never had problems using 8lpm. Gas lasts longer too!

I know your the sort of guy that lifts the hose up after welding to allow the gas to run back into the bottle....

Don't we all?

Collect up my filings too incase I need to stick it back on later to take up the slack..
