Probably wise. However, low skill level need not be a permanent
condition. Getting good MIG welds is not difficult, it just isn't as
easy as it might seem. It does require some practice and experience,
like any welding technique. It's particularly easy with MIG to make a
"pretty" weld with no strength -- and, with some experience, it isn't
difficult to avoid that error.
