I'm a Ray Charles welder like the rest of us, but are your welds hot enough?
Everybody keeps saying, "Are your welds hot enough?" What are you seeing to conclude that, so I can understand?
I'm going to take it they are not hot enough. After the last time someone asked me that, I decided to increase the amperage a notch above the recommendation for 3/16". I believe my welder was set at 130 or 140A for these passes. I'm using .030 wire.
EDIT: Did a little reading. Said a beginners mistake is not going slow enough and not getting enough penetration, resulting in a cold weld. I still don't know how to identify that though, apart from a break test.
