The Stovebolt Site Forums The Shop Area The Tool Chest Mig Welder (gas setting)

just wondering what psi that everyone is using have mine set a 10 should i raise it or go the other way.

way too much, stuff is too spendy to waste, 3 or 4 should get'er done

Bill

The gas settings are cubic feet per hour, not PSI. And it depends on if you are using straight CO2 or mix and the material you are welding and the wire. The more argon, the more gas you need. We start out at about 25 and go from there.

How much does wind affect welding outside. Do you just not weld in the wind, or do you try and compensate?

I know this depends on hard the wind is blowing, are there any guidelines.

Larry

wind affects it lots, hard to maintain a consistant 'bubble' of gas shrouding at the weld point if it's windy, only 'compensation' is go inside or pick another day

and re what Cren sez vs my numbers - I forgot the gauges in Canada are different, litres/minute

Bill

thanks for the info, use it in the barn so wind is not much of a problem, using the mix. just wondering what the rest of you were setting the the gauge at, seems to work ok at 10, may try to jump it up and see what happens then try the lower setting, thanks again

The manual for my Miller 180 requires setting the regulator at 20.

John

I set it at 25 psi in my mig and indoors.

Ganesh

moved it up to 20, seams to work a little better, thanks again for the input

If you need to mig weld outside, learn to cup the welding tip with the other hand. I use a heat shield in the palm of my hand to block the wind. You can block the wind with a sheet of plywoood. The wind will put holes in your weld.

My gas salesman made a funny statement when I asked him what I should set my gas pressure setting at...He said I sell gas so set it high, but you are buying the gas, so set it at the optimum level, to render the best weld, in the environment and conditions you are welding in.
