Hello
Can anyone tell me what the gas flow should be set at on a flowmeter using CO2 as the shielding gas? Is it set constant regardless of machine settings? The welding machine is an old Clarke 165E which I was given!
Thanks
Chris
10-12 litres/min normally. But if you've never welded before, or are inexperienced, upto 15lpm can help avoid small amounts of porosity.
Once set, leave it at that. No need to up it if you turn the machine up, its not an issue on a machine like that
