how much pressure do I use

any help would be usefull

I have the stainless rod.

 

Around 15psi

 

wtf??? 15psi??? lol


i use around 20-25 cfm depending on the size cup i use.

 

I would say 15-18

 

When doing stainless you want a lil extra, Id say 22-25 psi. Good Luck

what is this psi you guys are talking about... Your not shooting teh gas out as 15psi... Hence the name "flow" gauge not pressure gauge.

When the pressure is not flowing its psi, when its flowing its cfm from what I have been told.

I was told to use about 13-18cfm , and this was from a very reputable welder.

 

I was told from my welding teacher that it should be around 15-20cfm

 

I heard 20cfm

 

anywhere from 15-20 <U>CFH</U> depending on tungsten size, material thickness, ect. There really isnt one general setting, there are a bit of variables, those are a couple of them listed.

 

lol thats what i meant. dur on me. should have looked outside.

 

The answer is... use the lowest flowrate you can while still having full coverage of the weld area. If you use more than you need you're just wasting argon. I usually use 25cfm with a gas lense just because once in a while coworkers will open up a garage door while I'm welding and I don't feel like grinding out contaminated welds.

 

if you use more than 20 cfm (this is from my expierences) the gas tends to blow right out of the sides and you have no sheilding gas or very little, people then turn up the gas more which makes the problem worse, I myself use 15-20cfm its in the Miller Directions as well. Good luck.

 

I usually use 20+ cfm. It depends on what is going on around me, if the doors are open, what speed I'm welding at etc...Almost everyone is going to answer this question differently.
