DETAILS
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.
Features
- 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
- Select packaging and diameter are available meeting Buy America & American Iron & Steel (AIS) standards.
Typical Applications
- Seismic structural steel erection and fabrication
- General structural steel erection and fabrication
- Ship and barge fabrication
- Vertical up and overhead fillets and groove welds
Welding Positions
- All
Shielding Gas
