Get your gas bottle and retry. Pics look like your all over the place with your welding dots. You are using an auto darkening helmet aren't you? Only long time welders seemed to have the skill to flip their helmet down with a quick nod of their head and still place the weld correctly. Something I learned was the darkness shade of your helmet. I purchased both a tig and mig machines. Purchased a Hobart mask with a variable darkness control. Lowest setting was 9. When doing low amp sheet metal welds I couldn't see where I was going. My welds looked like yours. Purchased a new mask last summer that goes down to 7. Problem solved.
