oh and this statement is not completly true you should only pull if you don't need high peno that is fact I could send a copy to anyone whom wants it from our text.. please remember forum are just that a forum it is all opionion. In fact out of the three instructors on our campus we all have different thing that work for us but won't work for everybody. this welding thing is a very soft science.
