A scratched or spatter-marked front cover can make an otherwise functional welding helmet frustrating to use. The Bxmgr 0700000803 amber front cover lens pack gives ESAB Sentinel A50 owners five replacement covers that can be swapped when the current lens becomes difficult to see through. Its strongest points are the A50-specific fit, amber tint, and multi-pack convenience, but this is a third-party replacement rather than a genuine ESAB accessory, and it does not fit the Sentinel A60. This review explains the verified fit, listed viewing area, installation, limitations, and who should consider it.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: Sentinel A50 owners who want several amber replacement front covers ready for routine welding, grinding, or cutting work.
Bottom Line: The Bxmgr 0700000803 pack offers a practical way to keep replacement A50 front covers on hand. The main limitation is its narrow compatibility and third-party status, so confirm that your helmet is the Sentinel A50 before ordering.

What Is the Bxmgr 0700000803 Front Amber Lens Pack?
The Bxmgr 0700000803 is a pack of five amber outer cover lenses sold as replacements for the ESAB Sentinel A50 welding helmet. The 0700000803 number is also the part designation ESAB uses for the A50 amber front cover, which makes that number useful when checking compatibility.
The cover sits in front of the helmet’s auto-darkening filter. Its practical role is to act as a replaceable outer layer that receives scratches, dust, and welding contamination before the more expensive filter assembly. When the cover becomes badly marked or difficult to see through, replacing the cover can restore a cleaner viewing surface without replacing the entire helmet.
This Bxmgr listing is a third-party compatible product. It should not be confused with a genuine ESAB-branded 0700000803 pack.
Before You Buy: This product is listed for the Sentinel A50 and specifically excludes the Sentinel A60. It is also only the outer front cover, not the auto-darkening filter. Confirm your helmet model before ordering.
Who Should Buy It?
Best For
- Sentinel A50 owners who regularly replace scratched or spatter-marked outer covers.
- Shop welders who prefer to keep several spare amber covers nearby.
- Buyers comfortable using a third-party replacement instead of a genuine ESAB accessory.
Skip If
- You have a Sentinel A60 or another helmet model.
- You need an inside cover lens or replacement auto-darkening filter.
- You prefer genuine ESAB replacement parts only.
Fit and Compatibility
Compatibility is the most important buying factor. Amazon lists the Bxmgr cover for the ESAB Sentinel A50 and says it does not fit the Sentinel A60. The 0700000803 designation also corresponds to the amber front-cover position used by the A50.
Do not order by color or general shape alone. Different Sentinel helmet generations use different replacement parts. Check the model marking on your helmet and compare the required front-cover part number with 0700000803 before purchasing.
The seller lists a visible area of about 3.94 x 2.36 inches. That figure should be treated as the listed viewing area rather than the complete outside dimensions of the molded cover.
Amber Tint and Visual Clarity
The seller describes the amber cover as providing a naturally tinted view rather than a gray-green appearance. The amber tint is the main visual difference compared with a clear front cover and may appeal to welders who prefer that color presentation.
Keep the role of the cover in perspective. The outer amber cover is not the Sentinel A50’s auto-darkening filter and does not control the helmet’s shade response. The auto-darkening filter remains the component responsible for the helmet’s electronic shade operation.
A new outer cover can still make a noticeable practical difference when the existing one has accumulated scratches, haze, dust, or spatter. Replacing a damaged cover removes that obstructed surface from your line of sight, but it cannot correct a damaged filter, sensor problem, or other helmet fault.
Pro Tip: Keep unused covers in their packaging and away from grinding dust and abrasive tools. A spare lens that gets scratched in storage defeats the purpose of keeping replacements on hand.
How It Performs in Real Use
For Routine Welding
For regular A50 use, the biggest benefit is simple replacement convenience. When the installed outer cover becomes difficult to see through, you have additional covers ready instead of continuing to work through a badly marked lens.
The five-pack format is especially practical in a busy shop where front covers are treated as wear items. How often you need a new one depends on your process, work position, spatter exposure, and how carefully the cover is cleaned.
For Grinding
Grinding can expose the front of a helmet to fine abrasive dust and debris. A replaceable front cover helps keep that contamination off the filter assembly itself. You should still inspect the complete helmet before use and replace a cover that becomes badly scratched, cracked, or difficult to see through.
For Plasma Cutting
The Amazon listing also positions the amber cover for plasma-cutting use with the Sentinel A50. In this setting, the main reason to use the Bxmgr replacement is the same: it provides a sacrificial front surface while maintaining the A50’s normal viewing opening.
For Keeping Shop Spares
The multi-pack is most useful if your helmet sees frequent use. You can install one cover and store the remaining four as backups. An occasional hobby welder who rarely damages a front cover may get less benefit from buying several at once.
Installation and Care Tips
The product listing describes installation as removing the old cover and fitting the new one into place. ESAB’s A50 documentation also describes the helmet’s front cover as front-loaded, making replacement accessible without dismantling the complete helmet.
- Confirm the helmet first: Make sure you have a Sentinel A50, not an A60.
- Handle the viewing surface carefully: The seller recommends wearing gloves during installation to reduce the chance of scratching the new cover.
- Check the seating: Make sure the replacement sits correctly in the front-cover position before using the helmet.
- Inspect before each work session: Replace a cover that is badly scratched, cracked, warped, loose, or too cloudy for a clear view.
- Store spares separately: Keep unused lenses away from metal filings, grinding dust, and loose tools.
For cleaning and maintenance, follow the Sentinel A50 instructions and any directions supplied with the replacement covers. Avoid abrasive cleaning methods that could add scratches to the viewing surface.
Compatibility and Safety
A front cover lens is only one part of a complete welding helmet. You should use this replacement with a correctly assembled Sentinel A50 that has a functioning auto-darkening filter, inner cover, shell, and other required components.
Do not treat the Bxmgr cover as stand-alone eye protection or as a substitute for the auto-darkening filter. If the A50’s filter does not switch properly, the helmet is damaged, or the cover cannot be installed securely, stop using the helmet and follow the manufacturer’s service guidance.
The Amazon listing makes several marketing claims about natural color and reduced eye fatigue. Those statements should not be interpreted as proof of a separate safety certification for this aftermarket cover. The safer buying decision is to focus on correct helmet compatibility, proper installation, and the condition of the complete protective system.
Pros and Cons
Pros
- Five replacement front covers provide several shop spares.
- Uses the 0700000803 designation associated with the Sentinel A50 amber front cover.
- Seller-listed 3.94 x 2.36-inch viewing area aligns with the A50 viewing window.
- Amber tint gives you an alternative to a clear outer cover.
- Simple replacement format avoids replacing a complete helmet when only the outer cover is worn.
Cons
- Compatible with the Sentinel A50 only and not the A60.
- Third-party Bxmgr product rather than a genuine ESAB replacement pack.
- Does not replace a damaged auto-darkening filter, inside lens, or complete helmet.
Is It Worth the Price?
The Bxmgr 0700000803 pack makes the most sense as a value-oriented third-party replacement for A50 owners who regularly go through outer covers. Its value comes from receiving five replacements in one package rather than from premium branding or additional helmet components.
It is worth considering when its current price compares favorably with genuine ESAB replacements and you are comfortable using an aftermarket cover. The value is less convincing if you rarely replace lenses or if genuine ESAB components are a priority for your work environment.
Because Amazon pricing can change, compare the current cost per cover before deciding rather than buying based only on the multi-pack label.
How It Compares to Alternatives
The most direct alternative is the genuine ESAB 0700000803 amber front cover, which is also made for the Sentinel A50 and is commonly sold in five-packs. The genuine option is a better fit for buyers who want manufacturer-branded replacement parts, while the Bxmgr pack targets buyers comfortable with a third-party compatible option.
If you prefer a clear outer cover instead of amber, the ESAB 0700000802 clear front cover is the corresponding A50 clear option. ESAB also lists a heavy-duty amber front cover under part number 0700000824. These are different buying choices, so select the cover type and part number that match your needs rather than assuming all A50 lenses are interchangeable.
Frequently Asked Questions
Is this a genuine ESAB 0700000803 lens pack?
No. The Amazon listing identifies the brand as Bxmgr. It is a third-party compatible front cover that uses the 0700000803 designation associated with the Sentinel A50 amber cover.
How many amber lenses are included?
The current Amazon listing states that the package contains five amber front cover lenses. Older descriptions referring to a seven-pack do not match the current ASIN listing.
Will the Bxmgr 0700000803 fit the Sentinel A60?
No. The seller specifically lists this replacement for the Sentinel A50 and states that it does not fit the Sentinel A60. Confirm the model marking on your helmet before purchasing.
Is this the auto-darkening lens?
No. This is the replaceable outer front cover. The Sentinel A50 auto-darkening filter is a separate component inside the helmet and performs the electronic shade function.
Does 3.94 x 2.36 inches describe the full lens dimensions?
The seller presents approximately 3.94 x 2.36 inches as the visible or viewing area. You should not treat that number as a verified measurement of the complete molded cover’s outside dimensions.
When should I replace the front cover?
Replace it when scratches, clouding, damage, or contamination begins to interfere with your view or when the cover no longer fits securely. Replacement frequency varies with the work you do and how much spatter, dust, and abrasion reaches the front of the helmet.
Who should skip this replacement pack?
Skip it if you use a Sentinel A60, need an inner lens or auto-darkening filter, or require genuine ESAB replacement parts. It is also less compelling for occasional users who rarely need to replace an outer cover.
The Bottom Line
The Bxmgr 0700000803 five-pack is a practical option for Sentinel A50 owners who want several amber outer covers ready for replacement. Its strengths are straightforward A50 compatibility, multi-pack convenience, and the amber viewing option, while its main limitations are third-party construction and A50-only fit.
Buy it if those points match your helmet and replacement needs. Skip it if you use an A60, need a different helmet component, or prefer genuine ESAB parts.
