Hobart FabCOR Edge description: Edge is a metal-cored wire with fewer silicon islands than other metal-cored wires. On clean material, weld bead toe lines are almost completely free of silicon deposits. The weld bead face is virtually free from silicon island deposits. Together with exceptional low spatter rates, Edge will save time and money spent cleaning prior to painting, coating, or plating. The recommended shielding gas is a mixture of argon and carbon dioxide, with a minimum of 75% argon and a maximum of 95% argon. Arc characteristics improve with richer argon gases while spatter and fume levels decrease.
