Detalles
The choice for novice or experienced welders looking for an easy to operate self-shielded, flux-cored wire. The excellent arc control and accommodating weld puddle enable operators to make high quality weld deposits regardless of skill level.
Características
- Enhanced Feedability – New design increases wire stiffness to aid feedability and promotes smooth arc transfer
- Wire Snap-Off – Easy to break off wire end without tools for better re-strike
- Meets AWS D1.8 requirements for Demand Critical Welds – Three lot tests available at www.lincolnelectric.com/D1.8 to meet AWS D1.8 lot waiver requirements
- Effortless Operability – Welders of all skill levels benefit from the easy to control arc and forgiving weld puddle even out of position
