The ESAB 0700000480 Black Savage A40 is an auto-darkening welding helmet with external DIN 9 to 13 shade control, four arc sensors and a 3.93 x 1.96 in viewing window. It is aimed at MIG, stick and low-amp TIG work where you want simple controls rather than a touchscreen. This review covers what the specs mean in use, how the 0700000480 number relates to the 0700000490 listing, and who should look at a larger-window helmet instead. It is based on the Amazon listing, ESAB brochure data and retailer pages, not hands-on testing.
Quick Verdict
Best For: Welders who want a straightforward auto-darkening helmet with an external shade knob, four arc sensors and adjustable sensitivity and delay.
Bottom Line: The Black Savage A40 covers the basics well: DIN 9 to 13 shade, 1/1/1/2 optical class and a light shell. The trade-off is a moderate 3.93 x 1.96 in window, so skip it if you want a wide-view lens. Confirm the part number and kit contents on the current listing.

What Is the ESAB 0700000480 Black Savage A40?
The Savage A40 is a mid-range ESAB auto-darkening helmet. It uses a True Color lens, four arc sensors and an external shade knob, so you can change shade without lifting the helmet.
The black version carries part number 0700000480. One retailer lists 0700000490 as the current number and 0700000480 as the previous one, which suggests the two listings describe the same helmet family. Because ASIN pages and kits change, match the part number and package contents on the listing before you order.
Before You Buy: Check the shade range, kit contents, replacement cover lens availability and warranty on the current listing. Details can differ by seller and by listing version.
Key Features and Controls
Four Arc Sensors
Four sensors help the lens detect the arc from more positions, which matters when your hand, torch or the workpiece partly blocks one of them. You still need to keep the sensors clean and unblocked.
External DIN 9 to 13 Shade Control
The shade knob sits on the outside of the helmet, so you can change shade between jobs without taking the helmet off. Pick the shade from the filter chart for your process and amperage rather than by feel.
Sensitivity and Delay
Sensitivity sets how readily the lens reacts to arc light. Delay sets how long it stays dark after the arc stops. Both are set from inside the helmet, so make the adjustments before you start the job and test them on scrap.
True Color Lens and Optical Class
The lens is rated 1/1/1/2 for optical class and is sold with true-color technology. That should give a more neutral view of the work than older green-tinted lenses, although lighting and lens cleanliness still matter.
Power
The ESAB brochure lists a solar cell plus one replaceable CR2450 lithium battery, with a low-battery alert. Keep a spare battery in your kit.
Viewing Area and Weight
The brochure lists a 100 x 50 mm window, which is about 3.93 x 1.96 in. That is enough to follow a bead and the joint edges for most bench and garage work. It is smaller than the 3.93 x 2.36 in window on the Sentinel A50, so compare the two if you often weld in tight spots or over a wide joint.
The brochure weight is about 500 g, roughly 1.1 lb. Some listings show a higher figure because they report the shipping weight, so use the manufacturer number when you compare helmets.
Who Should Buy It?
Best For
- Garage and shop welders who want external shade control
- MIG, stick and low-amp TIG users who want to tune sensitivity and delay
- Buyers who prefer knobs to a touchscreen
Skip If
- You want a wide viewing window
- You need a shade range outside DIN 9 to 13
- You want memory presets or external sensitivity controls
Low-Amp TIG and Other Uses
Adjustable sensitivity is the feature that matters most for low-amp TIG, because a weak arc can fail to trigger a fixed-sensitivity lens. One retailer lists DC TIG use down to 5 A for this helmet. Test on scrap at your lowest working amperage before you rely on it.
For MIG and stick the settings are simpler: choose the shade from your process chart, set sensitivity high enough to trigger reliably in your shop lighting, and use a short delay for repeated tacks.
Pro Tip: Test the lens on scrap before every new job, and check it again if you move from a dim shop to bright daylight. Strong ambient light can change how auto-darkening lenses behave.
Setup Checks Before First Use
- Adjust the headgear so the helmet sits level without pressure points.
- Check that the battery is installed and the lens darkens when you strike an arc on scrap.
- Set sensitivity and delay for the process you are about to run.
- Inspect the cover lens, shell and sensors. Do not weld with a cracked or damaged helmet.
Safety, Lens Care and Maintenance
A helmet protects your eyes only when it is intact, correctly set and matched to the process. Wear gloves, flame-resistant clothing and ventilate the area; a helmet does not replace the rest of your PPE.
Clean the lens with a soft cloth and a cleaner approved in the manual. Replace scratched or spatter-pitted cover lenses and check the manual for the correct replacement part before ordering. For more on lens care, see the guide linked below.
Is It Worth the Price?
The price on the listing changes, so judge it against what you need. The Savage A40 makes sense if external shade control, four sensors and a light shell matter more than a large window or digital presets. If you weld every day and want a wider view, compare it with the Sentinel A50 or A60.
