DO YOURSELF and your projects a HUGE FAVOR,
anytime you run into a problem while welding ,
STOP,
ASK QUESTIONS,
CORRECT THE PROBLEM,
before PROCEEDING
and yes changing the polarity , the wire type or dia., the shield gas,the pressure, the weld rods, ETC,ETC. from what you know currently works,WILL almost always require other matched changes or youll have problems.
NO ONE knows everything, be smart and ask questions, and get answers from the PROS
