Buying Surplus Welding Rods - Cash Paid. Got a pile of welding rods you have no use for? Welding rods are heavy, bulky and I can make them go away and give you a few bucks in the process. I pay between 4 and 10 times the scrap value. Particularly interested in Lincoln 6013, 7014 3/32" diameter, FleetWeld 47 and anything stainless. Sealed 50lb cans preferred, but am open to other types and quantities. I can handle 50 to 2000 lbs.
