I practice my tig welding in the morning for an hour before I go to work. I notice that the arc is so much quieter and more stable when I switch from aluminum to steel (switch from AC to DCEN of course). All other settings are the same ( I do use gas lens). I did some research and I found this comments from weldingtipsandtricks.com.
"when you tig weld aluminum, too little flow or too much flow of shielding gas makes a big difference. and just a little too much flow, can make the arc really loud and make the arc erratic."
I set the flowmeter between 15-20 cfh. Do you change the flow rate between the steel and aluminum? Do you increase the flow rate for thicker metal?
