I should have got MIG then. A nice weld is beautiful to look at, but my needs are more practical. Still, I'll give it a go. My son wants to build a "mecha arm"

I should have got MIG then. A nice weld is beautiful to look at, but my needs are more practical. Still, I'll give it a go. My son wants to build a "mecha arm" with all sorts of spy features. This might be a good excuse to learn how to use it.
