Variable shade control. True-color clarity. High-temperature construction. Built for welders who need one lens to handle changing conditions.
The Næxon X-Series X682 Auto-Darkening Welding Lens brings modern variable-shade technology to the classic 2×4 lens format trusted by pipeline welders, pipe welders, and industrial craftsmen.
Designed for compatibility with most appropriate pipeliner and pancake-style welding hoods, the X682 combines a variable Shade 8–13 dark-state range, Shade 3 light state, adjustable sensitivity, adjustable delay, dual arc sensors, solar-assisted power, replaceable batteries, low-battery indication, and high-temperature housing in one compact welding lens.
Available in three viewing options:
Blue • Gold • HD
The X-Series is built for welders who don’t always burn at the same amperage, use the same process, or work under the same conditions.
One lens.
More control.
X-Series: Built for Variable Welding Conditions
Some welders know exactly what shade they want and rarely change it.
Others don’t have that luxury.
Different processes.
Different amperages.
Different materials.
Different environments.
Different jobs.
The X-Series X682 was built for the second kind of welder.
With a variable dark-state range from Shade 8 through Shade 13, the X682 allows the lens to be adjusted to suit different welding applications and conditions, subject to the shade protection required for the work.
Instead of changing lenses when the job changes, adjust the X-Series.
Variable Shade 8–13
The X682 provides a variable Shade 8–13 range, giving the welder control over the dark-state shade.
That flexibility makes the X-Series useful for welders moving between processes, amperages, and working conditions throughout the day.
Select the appropriate shade.
Set the lens.
Get to work.
Always select the shade required for the welding process, amperage, and applicable workplace safety requirements.
Shade 3 Light State
Before the arc starts, visibility matters too.
The X682 features a Shade 3 light state, providing visibility for setup, positioning, and inspection when the welding arc isn’t active.
That can be especially valuable for pipe welders trying to get positioned around a joint before striking the arc.
Hood down.
Get positioned.
See the work.
Strike the arc.
The lens takes it from there.
Enhanced Arc & Puddle Clarity
The X-Series is designed around the part of welding that matters most:
What you can see.
Its lens technology is engineered to reduce imperfections, excessive color saturation, blurriness, and distortion, helping provide a clearer view of the:
Base material. Joint. Arc. Weld puddle.
When you’re watching the edge of the puddle, reading the keyhole, or controlling your travel, visual clarity isn’t decoration.
It’s information.
True-Color Viewing Technology
Traditional welding lenses can heavily saturate the view, making the entire welding environment appear dominated by a narrow range of colors.
The X-Series crystal lens technology is designed to broaden the range of colors and hues visible in both the light and dark states.
This provides a more natural view of the welding area while helping the welder distinguish important details around the arc and puddle.
Less unnecessary color saturation.
More useful visual information.
Blue, Gold & HD Viewing Options
The Næxon X-Series X682 is available in three viewing options, allowing welders to choose the visual experience they prefer.
BLUE
The Blue X-Series provides a cooler-toned viewing experience for welders who prefer the distinctive characteristics of a blue welding lens.
Combined with variable Shade 8–13 control, it provides the X-Series technology with a unique visual character.
GOLD
The Gold X-Series brings the recognizable character associated with gold-style welding lenses into a modern variable-shade auto-darkening platform.
For welders who like the traditional gold-lens viewing experience but want modern controls, the Gold X682 provides that combination.
HD
The HD X-Series focuses on clarity and visual definition of the weld area.
It’s designed for welders who want a clean view of the base material, joint, arc, and puddle while taking advantage of the full variable-shade X-Series platform.
Blue. Gold. HD.
Choose your view.
Then dial in your shade.
Variable Sensitivity Control
Not every arc and environment behaves the same way.
The X682 includes variable sensitivity control, allowing the response of the auto-darkening system to be adjusted based on the welding application and surrounding conditions.
This helps the welder tailor arc detection to the work instead of relying on a single fixed sensitivity setting.
Adjustable Delay Control
The X-Series also provides adjustable delay control.
This allows the welder to personalize how the lens transitions after the welding arc stops.
Depending on the process, amperage, and working conditions, different delay settings may provide a more comfortable viewing experience.
Shade. Sensitivity. Delay.
The X-Series puts those controls in the welder’s hands.
Dual Arc Sensors
The X682 uses two arc sensors to provide consistent detection and switching.
This becomes particularly important in field welding where the relationship between the hood and arc changes constantly.
Welding the top of a pipe isn’t the same position as welding the bottom.
Neither is welding underneath equipment, inside a rack, or around structural steel.
Dual sensors help the lens recognize the arc as the welder moves through changing positions.
High-Temperature Housing
Welding lenses live close to heat.
The X682 incorporates a high-temperature housing designed to help reduce lens failures associated with heat exposure.
For pipeline, fabrication, and industrial welders spending long shifts around hot work, durability isn’t only about the lens surface.
The electronics and housing have to survive the environment too.
The X-Series is built with that reality in mind.
Solar-Assisted Power
The X682 uses solar-assisted power technology to utilize available light and help extend battery life during operation.
The solar system works alongside the lens’s battery power, improving power efficiency over the usable life of the lens.
Long shifts demand equipment designed for long shifts.
Replaceable Batteries
The battery reaches the end of its life.
The lens shouldn’t automatically have to.
The X-Series uses replaceable batteries, helping extend the overall usable life of the lens cartridge.
A built-in low-battery indicator provides convenient battery-status awareness so the welder can address a weak battery before getting into the next weld.
Built for Pancake & Pipeliner Hoods
The X682 brings these features into the traditional 2×4 welding lens format.
It’s designed for compatibility with most appropriate pipeline and pancake-style welding helmets that accept the corresponding lens dimensions.
That means welders can keep the hood style they know while upgrading what’s behind it.
Classic hood. Modern technology.
Includes Two Clear Polycarbonate Protective Lenses
Each Næxon X682 includes:
1 × Næxon X-Series X682 Auto-Darkening Welding Lens
2 × Clear Polycarbonate Protective Lenses
The clear protective lenses help protect the auto-darkening cartridge against sparks, spatter, debris, scratches, and everyday jobsite exposure.
Protective covers should be replaced when scratches, damage, or contamination begin interfering with visibility.

Built for Welders Who Change With the Job
The X-Series makes sense when your welding conditions aren’t identical from Monday morning through Friday afternoon.
One day you’re burning rod on heavy pipe.
Next you’re fabricating.
Amperage changes.
Process changes.
Position changes.
Lighting changes.
The X682 gives the welder control over shade, sensitivity, and delay so the lens can be adjusted as the work changes.
It’s built for:
• Pipeline welding
• Pipe welding
• Refinery work
• Plant shutdowns and turnarounds
• Power plant outages
• Shop fabrication
• Structural welding
• Industrial maintenance
• Field welding and repair
Næxon Expert Guide: X-Series vs. R-Series
The biggest difference is control.
The R-Series R682 is built around fixed-shade simplicity. Choose your preferred fixed shade—9, 10, 11, or 12—and use the auto-darkening system without needing variable shade adjustment.
The X-Series X682 gives the welder a variable Shade 8–13 range, allowing the dark state to be adjusted as welding conditions change.
The X-Series also provides a Shade 3 light state, variable sensitivity, adjustable delay, and high-temperature housing.
If you know exactly what shade you want and prefer simplicity, the R-Series makes sense.
If you want greater control from one lens across changing welding applications, the X-Series is built for that flexibility.
Why Variable Shade Matters
A single welding shade isn’t ideal for every welding situation.
Process, amperage, electrode, material, and other factors can affect the shade protection required for the operation.
The X-Series gives the welder a range from Shade 8 through Shade 13, allowing the dark state to be adjusted appropriately for different welding conditions.
That flexibility can be especially valuable for welders who perform multiple types of work throughout a shift.
One lens doesn’t mean one setting.
Why Auto-Darkening in a Pipeline Hood?
Pipeline and pancake hoods earned their reputation long before auto-darkening lenses existed.
They’re compact, straightforward, and familiar to generations of welders.
The X-Series doesn’t try to replace that tradition.
It upgrades what’s behind it.
With the hood down in the Shade 3 light state, the welder can position around the joint and prepare for the weld.
Strike the arc and the lens automatically transitions to the selected welding shade.
When the arc stops, the adjustable delay controls the transition back.
Keep the hood. Upgrade the view.
Care & Maintenance
Inspect the lens before every use.
Make sure the protective lenses are clean and free from excessive scratches, cracks, spatter, or contamination that could interfere with visibility.
Verify that the auto-darkening function operates correctly before welding.
Check the battery status and replace batteries when necessary.
Keep the arc sensors clean and unobstructed.
Do not use the lens if the housing, sensors, electronics, or lens itself are damaged or if the lens fails to darken correctly.
Replace clear protective lenses when they become damaged or visibility deteriorates.
