[TheForge] Speaking of cuts

[Michael H. Murphy]

A friend of mine, who is a truly expert welder and cutter, told me that most
of these types of problems are caused by a dirty cutting tip.  The smallest
imperfection in the cutting port can really screw up the flow, and cause all
sorts of problems with the size and cleanness of the cut.  I listened to
him, and I'm cutting a lot cleaner than I was before.  It's something to
think about.
