Gas flow setting test.

[redwine300]

Just completed a gas flow test but i am not sure of the results. I was hoping to start of with brown staining and as I gradually increased the flow find the optimum flow setting both for performance and cost. Would someone take a look and tell me what they think please? Does not appear to make much difference to the staining?

The problem with short runs is that you may just be using the gas between the torch valve and the regulator and there is not enough time for the initial surge to settle down to the set flowrate. so they all look the same.

maybe try slightly longer runs.

My Mig regulator has a green band from 10 to 25 lpm and I very rarely move it up near 10 unless I am welding outside on a windy day. I would run a few tests to see how low you can go and still weld acceptably then run a little higher than that.

Hi,

I tend to go by sound, and run mine at around 7 LPM especially in the workshop or on a calm day outside. Ten LPM sounds like it's way too much gas to me when I squirt it near my ear.
