Pros and cons
Pros
- Four arc sensors and a 100 × 60 mm (9.3 sq in) window, per Hobart's spec sheet
- Meets ANSI Z87.1-2015, CSA and EN 379 (Hobart)
- 560 g with simple analog shade, sensitivity and delay knobs
- Buyers say it rivals far pricier helmets for visibility
Cons
- Hobart does not publish an optical class
- Dark range 9–13 only — no 5–8 range for torch or plasma cutting
- Some buyers say the shell feels fragile; 2-year warranty
Our review
Hobart sells this as the Hobart Inventor auto-darkening welding helmet 770890 in black; graphic versions (770875, 771015) share the lens. Hobart's March 2024 spec sheet (283429) gives the Inventor a 3.94 × 2.36 in (100 × 60 mm) view, four sensors, 1/25,000 s switching, shade 3 light and 9–13 dark, a grind mode, 560 g, and ANSI Z87.1-2015, CSA and CE EN 379 compliance. That is more verified detail than most helmets twice the price.
The gaps are the optical class, which Hobart does not state (one retailer lists 1/1/1/2), and the shade range: without 5–8 it is not the helmet for plasma cutting or very low-amp TIG.
Buyers rate it highly for clarity and value, often comparing it favourably with dearer brands; durability gets mixed comments, with some finding the shell flimsy. Replacement headgear (770843) is cheap if yours wears out.
What buyers report
Summarised in our own words from Amazon buyer reviews. These are buyers' experiences, not our own testing.
- Hobby welders rate the image close to helmets costing far more, and like how comfortable it is to wear.
- One owner who also has a Lincoln Viking says both give an excellent image, but the Hobart is the better value.
- Owners note there's no external grind button; those who don't do production work say they rarely miss it.
