Lincoln Electric, ED040100, Stick Electrode, E7018-1 H4R, 3/32 in x 14 in, 50 lb Can

Lincoln Electric’s IronArc 7018-1 MR produces a soft, smooth and stable arc that offers an easy to manipulate weld puddle and good operator control, even for beginner welders! Compared to its Excalibur equivalent that is known for its deeper penetration profile, the IronArc 7018-1 is designed with a flat bead profile that has excellent wetting in the toes ideal for cap passes. By combining a high deposition rate, tested moisture resistance, and low spatter levels, these stick electrodes minimize post-weld clean up and allow for less hold times to optimize productivity.

Features

• Flat bead profile ideal for cap passes on pipe, groove welds, and pipe repair
• Q2 Lot®- Certificate showing actual deposit chemistry and mechanical properties available online
• Smooth arc transfer
• No intentional addition of zinc for moisture resistance
• Soft arc for ease of puddle manipulation
• Excellent wetting in the toes allowing for less hold times
