Here's something else that I'm personally guilty of... the "if a little is good more must be better syndrome!"




Welders commonly—and incorrectly—assume that a higher gas flow/pressure provides greater protection. In fact, excessive gas flow creates turbulence and swirling currents that pull in unwanted airborne contaminants (and it can cause arc wandering). Generally, err on the lower side of recommended shielding gas rates to ensure proper shielding coverage without turbulence.
