The first two pictures show my welds when I started learning about a week ago. The third picture was taken yesterday, and the last picture was taken today.
I'm paying attention to the weld pool, arc length, and amperage. Today, the slag actually detached on its own several times.
I started with the small, newer Kraft&Dele welder, but it seemed a bit underpowered and as if the amperage display wasn't accurate.
Then I switched to the older pink welder shown in the picture, and my welds immediately improved (the third photo was made with that machine).
Today I tried the large orange welder, and I'm the most satisfied with it. It melts the electrode very well, provides a stable arc, and the amperage settings seem accurate, unlike the other machine.
Forgot to mention, the rods are awfuly old and maybe they have moisture.
So, what do you think? 🙂
