On another forum, a long-time welder suggested using C02 gas with regular flux core wire as a way to keep the tip cooler and produce a better weld on mild steel than you would with solid wire and C25.
I was under the impression that the flux core wires intended for dual shield welding were not the same as the ones for ordinary flux core welding. Am I right about this?
I've also never heard of a need to keep the tip cool -- I wasn't aware that shielding gas had any function other than displacing the oxygen-laced air with a neutral gas to improve the quality of the weld. Does shielding gas play a role in cooling anything?
Thanks for any input.
