Hello bobwiggins, one other thing might be happening here, it is likely that your machine is an AC machine. Unless you have E7018 AC rod it won't run on this machine. Bill's suggestion for a nickel rod is definitely the way to go, Nickel 55 is a fairly common one and if possible you should probably try to use the 3/32" dia. ones. There are also many others that are available, if you have any connections with any welding repair shops in your area, you might check with them to see if they could spare a few rods. Possibly check with one of your area community college or vocational schools to see if they might give you a rod or two, I know many would be willing to do so. If not make a trip down to the local welding supply store and explain to them what you are trying to weld and depending on the brands that they carry you will probably end up with the correct rod for your project, don't be suprised though if the cost seems a bit outlandish. If this becomes too prohibitive cost wise, see if you can purchase a small amount of E309L stainless steel rod in the 3/32" dia. and give this a try. Good luck and let us know how things worked out. Regards, aevald
Hellow Bob, You have to go for nickie base electrode like Eutectic 2240, Hilco pu/ni, ok 92.58. Normaly this kind rods are expensive. And you have to think of max. output of your machine and the diameter that you are expect to use too. Sydney
