I'm down to my last few Oerlikon Supercord 2.5mm rods and have two boxes of Murex Zodian universal 6013 rods, but I'm not getting a good weld at all with the Murex. The main problem is excessive inclusion along the root of the weld on 90 degree joints. The weld pool appears fine, but I can see when cooling there's the telltale red line glowing along the weld. Cleaning off reveals a weld bead each side with a line of flux/slag running down the middle with zero penetration. Increasing the current etc hasn't helped. Going back to the Supercord and the welds are entirely trouble-free, with the slag peeling away on its own leaving an even, smooth weld. I can't figure out why there should be such a difference between the rods as both are reputable brands.
Also, what happened to Supercord? The name has disappeared.
