Lincoln 125hd flux core settings problem

admin

Hello to everyone 🙌🏼Thank you for any help/advice you can provide!I am welding some box tubing (095) with a Lincoln 125 flux core welder. I have welded with arc and mig in the past, while not an expert I can (usually) lay down a decent bead. This welder is definitely challenging for me to get the settings right. When welding with D amperage setting I'm getting significant blow through.  When welding with the C setting I'm getting a tall bead with not enough penetration. Essentially D is too hot and C is too cold. Any ideas/suggestions?Thank you 🙏🏼
