DETAILS
Lincoln Electric’s IronArc 7018 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 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
- Soft arc for ease of puddle manipulation
- Smooth arc transfer
- Excellent wetting in the toes allowing for less hold times
- Flat bead profile ideal for cap passes on pipe, groove welds, and pipe repair
- No intentional addition of zinc for moisture resistance
