DETAILS
Designed for high speed welding of specialty coated steels. Recommended for single pass welding on material thicknesses from 0.8 to 4.8 mm (0.030 to 3/16 in).
Features
- Designed for high speed welding of specially coated steels
- Soft, consistent arc
- Porosity resistant
- Excellent overlapping capabilities
- Ideal for robotic applications
- Warning: NR-5 is NOT recommended for welding multiple passes.
- Notes: The preferred drag angle is 15°, however, NR-152 is capable of welding at zero drag angle, facilitating easy fixturing in automatic applications.
