The Hobart 770580 face shield lens is a shade 3 replacement window, about 15.5 by 8 inches, made for the Hobart 770118 face shield. Hobart lists it as a shaded replacement shield. It is for brazing, torch work and similar low-intensity glare, not for arc welding. If you need a lens for MIG, TIG or stick welding, this is the wrong shade.
This review is based on Hobart’s product page, the Amazon listing and general face-shield knowledge. We have not tested the lens.

What a shade 3 face shield lens is for
A face shield with a shaded window gives full-face coverage against flying particles and reduces glare from light heat sources. Shade 3 is a light tint. It suits tasks such as light torch brazing, soldering with a torch, or working near a bright flame, depending on your process and the lens chart. Always check the shade recommendation for your specific task.
It is not a welding filter. Arc welding commonly needs shade 10 or darker, and oxy-fuel welding or cutting uses much darker goggles or lenses than shade 3. Using shade 3 for arc work can cause arc flash burns.
How to check this lens fits your face shield
- Confirm that your shield is the Hobart 770118 or a model that uses a 15.5 by 8 inch window. Look at the manual or part number on the shield.
- Measure the window of your current lens: width, height and mounting holes or slots.
- Compare the measurements to the 15.5 by 8 inch listing size, including any curve.
- Check the seller. A listing sold by a third party may use the Hobart number to describe a compatible lens, not a Hobart-branded part.
- Check the pack size so you know how many lenses you are getting.
How to replace a face shield lens
- Remove the shield from the headgear or carrier and lay it flat.
- Release the clips, rivets or retaining strips following your model’s instructions.
- Slide out the old lens and wipe the frame clean.
- Fit the new lens with the protective film removed, then re-secure it so the edges are flush.
- Check that it does not rattle and that the edges leave no gaps.

Frequently Asked Questions
What is the Hobart 770580 used for?
It is a shade 3 replacement lens, listed by Hobart for the 770118 face shield. It gives a lightly tinted full-face window for tasks that need glare reduction but not an arc welding filter.
Can I use shade 3 for welding?
No. Shade 3 is far too light for arc welding. MIG, TIG and stick welding need a dark filter, commonly shade 10 or higher, so use a proper welding helmet or filter for those processes.
Does it fit every face shield?
No. Hobart lists it for the 770118 face shield and the window measures about 15.5 by 8 inches. Compare dimensions and mounting style with your shield before ordering, and be aware third-party sellers may offer similar lenses.
How do I know when to replace the lens?
Replace it when scratches, pitting or haze reduce visibility, or if you see cracks or deep gouges. Do not keep using a damaged lens because it can fail from impact.
Bottom line
The Hobart 770580 is a useful replacement if you own the 770118 shield and need a shade 3 window. Keep it away from arc welding, and confirm the seller and pack size on the Amazon listing.
