Welco & MG welding rods

[yooper]

I was rummaging around the house and forgot I had a cache of cast iron rods stored in bottom of the linen closet , I came across nib MG 200 cast iron 1/8 stick and several 10 lb packs { sealed } of Welco 94 cast iron rod .
Looking online I don't find any info on either , the MG was made by MG Welding Products , in Menominee , Wi , has anyone heard of either of these brands ?
I'm sure I've had them for at least 25 years , lol
