Take your welding projects to the next level with the Esab Dual Shield 7100 Ultra .045 Flux Core Wire. Known among professional welders for its superior operator appeal, this gas-shielded flux-cored wire makes all-position welding feel effortless. Whether you are laying down beads on heavy structural beams or performing intricate repairs on earth-moving equipment, this wire provides the control and consistency you need to produce X-ray quality welds.
The "Ultra" in the name stands for ultra-performance. You will notice the difference immediately in the arc stability. It runs smooth and hot, digging in for good penetration while maintaining a manageable puddle, even when welding vertical-up. The slag system is designed to freeze quickly to support the puddle in out-of-position work, yet it peels off easily—often curling up on its own—saving you from excessive chipping and wire brushing. This makes it a favorite for welders who take pride in the appearance of their finished work.
Flexibility is key in the shop or the field. That is why the Dual Shield 7100 Ultra is formulated to run on either straight CO2 or an Argon/CO2 blend. If you are looking to save money on gas, 100% CO2 works great. If you want an even smoother arc with less fume, switch to a 75/25 mix. Packaged in a substantial 27.2 kg spool, this wire is ready for long shifts and heavy deposition work, ensuring you spend more time burning wire and less time swapping spools.
