    Welding rod question: I buy stainless steel rod in quantity. It is marked Lincoln LEO7236 SS 312-16 1/8". Most of the one pound boxes are BLUE MAX 2100. However, I run into boxes of NICHROMA. End of BLUE MAX is blue and NICHROMA is red. Are they the same rod, just a different supplier to Lincoln?

    I had checked out the Lincoln Welding site. I can find lots of information on the Blue Max series but come up empty on Nichroma. I even double checked the spelling from one of the rods.

    I will try their customer service.

    I suspect it is an equivalent rod intended for high carbon and disimilar metals.
