Hobart 770478 E7018 Stick Welding Electrode 1/8" Diameter 5 lb Box

The Hobart 770478 E7018 is a professional-grade low-hydrogen stick welding electrode designed for high-strength welding applications on low, medium, and high-carbon steels. This 1/8" diameter electrode comes in a convenient 5 lb. box and is engineered for use in all welding positions, making it ideal for structural steel fabrication, automotive repairs, construction projects, and farm equipment maintenance.

Key Features:

• 70,000 PSI tensile strength for robust, durable welds on critical applications
• Low-hydrogen formulation reduces the risk of weld cracking and hydrogen embrittlement
• Ideal for out-of-position welding and tacking with excellent arc stability
• Runs on AC or DCEP (reverse) polarity for versatile power source compatibility
• Smooth, quiet arc operation with minimal spatter for cleaner welds
• Good slag removal and easy weld puddle control
• Medium penetration characteristics help prevent lack of fusion defects
• Excellent restrike capabilities for consistent arc starts

The E7018 classification indicates this electrode meets AWS specifications for structural steel welding. The "70" denotes 70,000 psi tensile strength, the "1" indicates all-position capability, and the "8" refers to the low-hydrogen coating and medium penetration profile. This electrode is suitable for construction, structural fabrication, pipe welding, heavy equipment repair, and general steel joining applications. Not recommended for low-voltage AC welders.
