The Miller Digital Infinity is the smartest of the premium range of helmets. It also boasts the largest viewing area of 13.4 square inches and a nice range of graphics. Miller items have always been popular in the trade. It has the largest price of the three latest reviews between the Miller Digital Infinity, ESAB Sentinel A50 and the Lincoln Viking 3350 4C. Here is my Miller Digital Infinity review hood after 6 months of use.
The Digital Infinity’s Lens
The light state of the hood is impressive at a shade 3. Thanks to the latest technology from Miller, branded as ClearLight. The clearlight makes it easy to see the job you are working on without lifting up your hood. It eliminates the need to replace it with a clear face shield for grinding, saving time and frustration.
Having a viewable area of 4.4 x 3.1 inches or 112 x 78 mm, you have an excellent field of vision, making it easier to maneuver around the job with the hood still down safely. We have all stumbled over a lead with our helmets down now haven’t we?
Miller has fitted 4 arc sensors to the Digital Infinity to ensure that the lens is switched to weld/cut mode if an arc has been struck. A standard in premium in most helmets but the cheaper auto-darkening has to save money where they can. But in a professional setting or serious DIY setting, 4 arc sensors are recommended.
Mode Selection on The Digital Infinity
You simply cycle through the Digital Infinity’s 4 different modes on the digital LCD by using the on/off/mode button. A bonus over other helmets as you can still have your welding gloves on.
It is in weld mode when you first turn the hood on. With a range from DIN 8-13, the adjustment buttons have a tactile feel. As I mentioned earlier, they can be pressed with your welding gloves on, I have repeated that because it is such a great feature. It also has an easy to read display and LTR / DKR buttons to cycle through the shade you need.
To engage grind mode on the Digital Infinity you have to lift the hood to press on. This is a downside to the other premium hoods I have reviewed. This is the helmet’s biggest con. When grind mode has engaged, a red LED in the display flashes every 3 seconds to indicate the helmet is in grind mode.
Whether you are gas cutting or using a plasma cutter the Digital Infinity has got you covered. With a range of DIN 5 – 9. No more looking around for your dusty old gas cutting goggles or squinting with clear safety glasses.
This feature is new, Miller has introduced X mode for if you are welding outside a lot. The hood relies on the electromagnetic field generated by the arc to switch the lens to weld mode. In bright sunlight conditions, the arc sensors may not detect the arc, resulting in a flash.
This is perfect for heavy machinery field repairs, pipe welding, or construction sites.
The Infinity has the adjustment next to the shade. By pressing the SHORT / LONG you can choose 0.01 to 1.0 in increments of 0.01 of a second. I found .5 to be the sweet spot. It is long enough to protect your eyes, but not long enough to get bored.
This is to adjust the lens sensitivity to going from its light state to the cut or weld mode that has been selected. Lower amp TIG or low voltage MIG requires more sensitivity.
In a workshop environment, you can raise the sensitivity level to stop your helmet going into weld mode from a co-workers arc from across your shop.
The amount of light in your work area also plays a part in the adjustment. Miller makes it easy with the excellent LCD display and dedicated LESS / MORE buttons.
Added features of the Digital Infinity Lens
These extra features actually blew me away when I first looked at the helmet. Included in the digital readout is a clock, a timer, and an alarm to set for meal breaks or reminders. Plus my favorite arc on time to track how much welding you have done.
The helmet also has different language options. I didn’t go into the language settings in case I changed mine and couldn’t get it back to English.
Miller Digital Infinity’s Headgear
The headgear of the Miller Digital Infinity is very comfortable. Inside the box it has an additional cushion that clips onto the two head supports. The ratchet adjustment keeps it’s tension and pivots to perfectly fit the back of your head.
To adjust the forwards and backward of the helmet there are black tabs on the top and bottom of the hinge assembly. Simply press them together to easily slide the headgear into a comfortable position.
It is a great feature if you wear a half-mask respirator. The helmet tends to sit off the respirator if there is no adjustment. This is also handy for overhead and other uncomfortable welding positions.
Digital Infinity Weight
With the huge 13.4 sq inch lens and digital display, the weight has crept up to 23 oz / 1.44 lbs or 653 grams. The headgear does a good job of spreading the load of the hood on your head, but it could be an issue for some people.
The Digital Infinity is 200 grams heavier than my old flip helmet so I did notice the difference but it’s not a concern for me personally.

Final thoughts On The Miller Digital Infinity Review
The Digital Infinity is a great welding helmet. The shade 3 Clearlight lens was the selling point for me. The construction of the helmet is robust so I have no hesitation in using mine in my full time job as a coded welder.
It will handle being out in the field using it for arc gouging or being in a dairy factory doing sanitary stainless steel tube in a food industry factory. The clarity of the lens is as good as you can get.
