Hi, I am brand new to welding and need to weld some square aluminum tubes together for a project. I have been practicing creating lines, but they look terrible. I have messed with the amount of argon shielding gas, the wire speed, and the voltage, but all welds look similar to the attached picture.
I am using a millermatic 211 with the spool gun shown below.
I also attached a picture of a bunch of different lines I tried with various settings.
Thank you for any help!
