I also don't understand the "Experienced Welder" comment. Would seem like a good welder would be what is needed, plenty of them on here. Some experienced welders may be bad welders. Depends intirely on how they were experienced

How true this is! Someone who has welded for many years, still may not be a good welder. It seems nowadays that anyone that owns a welder,suddenly becomes a "welder".
Without understanding the correct procedures when welding, as to not create undercuts in welds,can only lead to problems,like stress cracks. Undercuts are one of the most common failures in mig welding tubing.
