The Tough One™ #103 / The Ultimate Low-Hydrogen Electrode

The Tough One #103 special Chem-A-Tized2 flux coating changes the way welders think of low-hydrogen electrodes. It operates at lower amperages with better puddle control than all previous low-hydrogen electrodes. Additions of nickel and molybdenum make the weld deposit tough and strong, but still machinable.

• Improved weldability – operates like a low-hydrogen rod should, with an easy-to-see puddle, extremely low spatter and easy slag-removal. It is easy to use out-of-position and the weld goes where you direct it… it’s a welder’s dream rod.
• Superior weld toughness – designed for tough maintenance applications.
• Versatile – designed for welding mild steel, low alloy steel, free-machining steel, high-strength steel…all with one rod.
• New Chem-A-Tized2 coating provides better arc control, low spatter and better bead appearance
• This low-hydrogen electrode is designed with an inorganic covering to reduce the presence of diffusible hydrogen.
• Hydrogen is detrimental to the physical properties of many steels. E7018 is an all-position, mild steel, low-hydrogen coated electrode that reduces the need for preheat on heavy sections and can be used on high strength, high carbon and some low alloy steels.
• E7018 electrodes are characterized by a smooth quiet arc, low spatter and medium penetration. Store dry and sealed or in a rod oven.
