What's red writing on a stick electrode mean?

I searched it and couldn't find an answer. 6013. 3/16. Black seems to weld better than red. No idea where the red came from. Might have gotten wet? Does the red writing have any significance?

perhaps if we saw what you are referring to it would help.

There all combinations of colors. Blue, red, black, white, etc. The only thing important about the color is for the maker. The numbers and letters tell you all you need to know as a user.

"writing" doesn't seem to have significance. Actual rod color does. Red powder 6010 doesn't work as well as grey 6010 for instance. Both do the job, but higher spatter and other issues make some prefer the grey.

Often different manufacturers have different color printing on the rod.

You may just be looking at 2 different brands - and they do often weld different.

Otherwise, you could be remembering references to the red brick color lincoln 6010 vs. the grey color lincoln 6010 5p+

(I kind of like lincoln's red 6010 - not sure why )
