Good point! When in doubt I always do some practice welds with
similar (scrap) metal in similar configuration to see what settings
are gonna work. It doesn't take long to discover what works with
the "usual stuff": flats, angle, channel and tube of thickness from
1/8" to 1/4" with some round bars now and then.


So, you make practice welds, and then you try to break them, is that
right?

I have certainly done this but I don't do it much anymore unless it's
easy. I might section one (cut with bandsaw) to inspect it. I kinda
know what fused metal looks like by now.
