Arc Color with Flux Core Mig
Posted: Sat May 21, 2016 7:56 pm
During my latest 0.35 flux core welding project I noticed the color of the arc occasionally changed from bright white to yellowish while running line under good environmental conditions. The appearance of the weld shows a slight change where the weld color changed. Any idea what's going on? I'm welding very clean (I think) 1/8" flat stuff. The temp is high and the wire speed medium. Most welds look good for what I can do with a 110v-140amp MIG.
