Hi Guys, So my old Sealey mightymig 130xt mk2 is up and running. It's currently on CO2 but im getting some argoshield from Hobbyweld next week. I used the lowest power setting of 35A and 0.6mm wire. The metal was 0.8mm thick of which i butt welded the 2 bits together. Apart from the test at the bottom this is basically my first ever weld. See the welds below. What do you guys think? They seem quite raised but penetration seems 'okay', maybe a bit too much. Was i holding the welder there for too long? Cheers! Harry.
