Mariss & others,

Sorry, I was cleaning up a while back and must have tossed the
magazine. I went to www.aws.org and did a search, and I think this

The American Welding Society's Welding Journal

Article Name: A Study on Arc Characteristics and Its Application to
Height Control in Plasma Arc Cutting
Author: T.J. Lho D.G. Um S.J. Na
