A scratched or spatter-damaged front lens can make an otherwise usable welding helmet frustrating to wear. This review looks at the Bxmgr 5-pack of 0700000803 amber front cover lenses sold for the ESAB Sentinel A50. The pack gives you several replacement covers, but it is a third-party compatible product, not the auto-darkening filter and not a universal helmet lens. You will learn what it fits, what the amber cover does, how to install it safely, and when a genuine ESAB option may be the better buy.
Quick Verdict
Rating: Recommended with caveats
Best For: Sentinel A50 owners who want a lower-cost five-pack of amber front cover replacements.
Bottom Line: This pack is useful for keeping spare front covers ready when scratches or spatter reduce visibility. Its main tradeoff is that it is a third-party compatible part, so you should verify the 0700000803 part number and your exact A50 helmet before ordering.

What Is the Bxmgr 0700000803 Front Cover Lens Pack?
This listing is for five amber front cover lenses made by Bxmgr for use with the ESAB Sentinel A50 welding helmet. The 0700000803 number matches the amber front cover part designation used for the Sentinel A50, but the product linked in this article is a compatible aftermarket pack rather than a genuine ESAB-branded pack.
A front cover lens sits outside the helmet’s auto-darkening filter. Its job is to take the abuse from sparks, dust, and spatter before those hazards reach the more expensive filter assembly. Replacing the cover when it becomes pitted, cloudy, or deeply scratched can restore a clearer line of sight without replacing the entire helmet.
Before You Buy: This five-pack is listed for the ESAB Sentinel A50 only. It is not listed for the Sentinel A60, and it does not replace the helmet’s auto-darkening filter. Confirm your helmet model and the 0700000803 part number before ordering.
Who Should Buy It?
Best For
- Sentinel A50 owners who regularly replace scratched or spatter-marked front covers.
- Shop welders who prefer to keep several spare lenses near the work area.
- Buyers who want an amber, third-party alternative to a genuine ESAB five-pack.
Skip If
- You use a Sentinel A60 or another welding helmet model.
- You need the inner cover lens, auto-darkening filter, or complete helmet.
- You only buy genuine ESAB replacement parts.
Feature-by-Feature Review
Fit and Compatibility
Compatibility is the most important buying factor. The Amazon listing identifies these covers as replacements for the ESAB Sentinel A50 and states that they do not fit the Sentinel A60. The part number is 0700000803, which is associated with the A50 amber front cover.
Do not order by shape or color alone. ESAB uses different cover lenses for different helmet generations, and a lens that looks close may not seat correctly in the retaining area. Check the label on your helmet, your manual, and the old cover’s part number before you buy.
Five-Pack Convenience
The pack contains five front covers. That quantity makes sense for active welding shops because a cover lens is a wear item. You can install one and keep the remaining covers sealed and protected until the current lens becomes difficult to see through.
A multi-pack is less useful for an occasional welder who rarely damages a lens. In that case, the better choice may depend on the current price difference between this pack and a genuine ESAB pack.
Amber Cover Design
These replacement covers have an amber tint. The listing promotes a natural-looking view and less gray-green color, but the cover itself is not the helmet’s auto-darkening technology. The Sentinel A50’s filter assembly controls shade response and optical protection.
The amber cover may change how the work area looks compared with a clear front cover. Some welders prefer that tint, while others want the most neutral view possible. A clear 0700000802-style cover is worth comparing if color neutrality matters more to you.
Viewing Area and Clarity
The seller lists a visible area of about 3.94 x 2.36 inches, which aligns with the Sentinel A50 helmet’s stated viewing area. That figure describes the visible window rather than proving the full outside dimensions of the replacement piece.
Clarity will depend on the condition of the cover, correct installation, and how you clean it. A new lens can help when the old cover is hazy or scratched, but it cannot correct damage inside the auto-darkening filter or problems with the helmet’s shade controls.
Build and Expected Wear
Front covers are designed to be replaced as they collect scratches and spatter. This product’s main value comes from having several covers available, not from promising that one cover will last for a fixed period.
Service life varies with welding process, amperage, work position, spatter level, and cleaning method. Grinding dust and wiping with a dirty rag can mark a lens quickly. Store unused covers flat in their packaging and away from abrasive tools.
How It Performs in Real Use
For Routine Shop Welding
During regular MIG, TIG, or stick work, the front cover acts as the first barrier between the work area and the A50 filter. Keeping the cover clean helps you follow the joint and inspect the puddle without looking through a layer of fine scratches.
For High-Spatter Work
Flux-cored welding and poorly tuned MIG settings can expose the helmet to more spatter. A five-pack is practical in that setting because you can replace a badly pitted cover instead of trying to polish or scrape it. Never use a sharp tool on a lens while it is installed in the helmet.
For Grinding and Plasma Cutting
The cover can remain in place while you use compatible A50 helmet modes for grinding or plasma cutting. The cover does not set the shade or make a process safe by itself. Use the correct helmet mode and shade settings from the ESAB manual for the task.
For Mobile Work and Spare Storage
Mobile welders can keep one or two spare covers in a clean, rigid sleeve inside a tool case. Loose storage next to electrodes, grinding discs, or metal parts can scratch a replacement before you install it.
Pro Tip: Write the helmet model and part number on the storage sleeve. That simple label helps prevent an A50 cover from being mixed with A60 or other helmet parts in a shared shop.
Installation and Care Tips
- Confirm the helmet model. Look for Sentinel A50 identification and compare the old cover with part number 0700000803.
- Follow the ESAB manual. Remove and install the front cover using the helmet maker’s procedure. Do not force tabs or retaining parts.
- Wear clean gloves. Fingerprints, grit, and metal dust can reduce clarity or scratch the new surface.
- Inspect the seating area. Remove loose debris before fitting the new cover, then make sure the cover sits flat and secure.
- Test the complete helmet. Before striking an arc, inspect the shell, cover, inner lens, auto-darkening filter, sensors, and controls.
- Clean gently. Use a soft, clean cloth and a cleaning method approved in the helmet manual. Replace the cover when cleaning no longer restores a clear view.
A common mistake is treating the front cover as permanent. Deep scratches, heat damage, cracks, and heavy pitting are reasons to replace it. Another mistake is assuming that a new cover fixes every visibility problem. If the view remains distorted or the filter does not darken correctly, stop using the helmet and inspect the full system.
Compatibility and Safety
This product is a replaceable outer cover, not certified eye protection by itself. Use it only as part of a complete, correctly assembled Sentinel A50 helmet with a functioning auto-darkening filter and inner cover. Never weld with the front cover missing, cracked, loose, or installed incorrectly.
Check the helmet before each work session. If the auto-darkening filter fails to switch, the shell is damaged, or the lens assembly will not lock into place, stop and follow ESAB’s service guidance. Replacement covers should protect the filter, but they do not repair electrical, sensor, battery, or filter faults.
Pros and Cons
Pros
- Five replacements give active welders several spares.
- Uses the 0700000803 part designation for the Sentinel A50 amber front cover.
- Listed visible area matches the A50’s approximately 3.94 x 2.36-inch viewing window.
- Amber tint offers an alternative to a clear front cover.
- Replacing a worn cover costs less than replacing a complete helmet or filter.
Cons
- Third-party compatible product, not a genuine ESAB-branded pack.
- Limited to the Sentinel A50 and specifically listed as not fitting the A60.
- Seller language about true color may overstate what a replaceable outer cover controls.
Is It Worth the Price?
This pack can offer strong value when you use a Sentinel A50 often and go through front covers regularly. Five replacements reduce the chance that a damaged cover will stop work while you wait for a new one.
The value is less clear for occasional use or for buyers who want only genuine ESAB parts. Compare the current cost, seller support, and return terms with the genuine ESAB 0700000803 five-pack. The third-party pack makes the most sense when compatibility is confirmed and the price difference is meaningful.
How It Compares to Alternatives
The closest alternative is the genuine ESAB 0700000803 amber front cover five-pack. It is the safer choice when factory branding and documented fit matter more than price. The ESAB 0700000802 clear front cover is better for A50 owners who prefer a clear rather than amber outer lens.
Do not confuse either front cover with the 0700000808 inside cover lens or the complete auto-darkening filter. Those parts serve different positions in the helmet and are not interchangeable.
Frequently Asked Questions
Is this a genuine ESAB replacement lens?
No. The linked Amazon listing identifies the brand as Bxmgr. It is sold as a third-party compatible replacement using the 0700000803 part designation for the Sentinel A50 amber front cover.
Will it fit the ESAB Sentinel A60?
The seller specifically states that it is not for the Sentinel A60. Buy it only after confirming that your helmet is a Sentinel A50 and that 0700000803 is the required front cover part number.
Does the pack include five lenses?
Yes. The listing describes a five-pack of amber front cover lenses. Check the package as soon as it arrives and keep unused covers protected from dust and scratches.
Is this the auto-darkening lens?
No. It is the replaceable front cover that protects the auto-darkening filter. It does not control shade, sensitivity, delay, or arc detection.
When should you replace the front cover?
Replace it when scratches, cracks, clouding, heat damage, or spatter make the work area harder to see. There is no single replacement schedule because wear depends on your process and work environment.
Can you use it for grinding or plasma cutting?
The front cover can stay installed while the Sentinel A50 is used in an appropriate operating mode. The cover does not determine the safe shade or mode, so follow the helmet manual for grinding, plasma cutting, and welding settings.
What should you check after installation?
Make sure the cover sits flat, locks securely, and has no protective film or debris blocking the view. Then inspect and test the complete helmet before striking an arc.
Should you choose amber or clear?
Choose amber if you prefer the tinted outer cover used by the 0700000803 design. Compare a clear 0700000802-style cover when you want a more neutral-looking outer lens.
The Bottom Line
The Bxmgr 0700000803 five-pack is a practical choice for Sentinel A50 owners who need several amber front cover replacements and are comfortable using an aftermarket part. Skip it if you own an A60, need an inner lens or auto-darkening filter, or prefer genuine ESAB parts. Its main strength is five-pack convenience, while its main limitation is model-specific, third-party compatibility.
