OVERVIEW

Upgrade Your Hood

Stop flipping your hood and start seeing the arc clearly with the ArcOne Singles Duo Pack. If you love your old-school pipeliner or pancake hood but want the modern convenience of auto-darkening technology, the Singles S240 line is the legendary solution. This special "Duo" pack gives you the best of both worlds by including two complete lenses: one Shade 11 and one Shade 12. Whether you are burning 7018 rod hot and heavy or doing precision TIG work, you have the right lens for the job right in your tool bag.

Crystal Clear View

The ArcOne Singles are famous for their clarity. When you aren't welding, the lens sits at a bright Shade 3, letting you grind, chip slag, and set up your joint without lifting your helmet. As soon as you strike an arc, it snaps to dark instantly. No batteries to die on you, no switches to break—just pure solar power that works whenever you do. These lenses drop right into any standard 2x4 retainer (like the Fibre-Metal Pipeliner or Tigerhood) and are thin enough to fit easily behind your clear cover lens.

Why Buy the Duo?

Welding conditions change. Sometimes a Shade 11 is perfect for visibility, but when you crank up the amps, you need the extra protection of a Shade 12 to keep your eyes cool. Buying the S240-11/12 Duo pack ensures you are never caught without the right shade. It's the ultimate upgrade kit for the serious welder who demands performance and versatility from their gear.
