Hello, no they are all horizontal welds. Dark area is a the end of weld. But I post a new photos, here the welds are all dark. Here I tried to change travel speed and parameters machine. I clean the weld with a grind and
cup brush. I use a helvi wire.
Hello,
I am trying FCAW and I want ask, what depends on the dark color that I notice in my weld?
It's a problem with parameters machine? Travel speed? I tried change my travel speed and
to increase the tension but the color does not change.
Thnaks in advance.
