Overview
The Lincoln VIKING 3350 Series is Lincoln Electric’s premium auto-darkening helmet line, and the K3034-4 model leads the charge with an ideal mix of high-performance optics, wide viewing area, and long-lasting comfort. Powered by both solar and replaceable batteries, it supports all major welding processes. Its durable construction and intuitive features make it a top choice for welders who need uncompromising performance on the job or in the workshop.
Our Take on the Product
In my experience, the Lincoln VIKING 3350 helmet stands out the moment you put it on. The X6 Headgear truly earns its reputation—it distributes the helmet’s weight so evenly, you almost forget you’re wearing it. When welding, the clarity and color accuracy through the 4C lens is a game-changer. You see the puddle, arc, and base metal in detail you’d normally only dream of.
Pros:
- Exceptional optical clarity (1/1/1/1)
- Huge viewing area—feels almost cinematic
- External grind control saves tons of time
- Extremely comfortable fit for long sessions
- Comes with lots of extras (bag, lenses, bandana)
Cons:
- Slightly heavier than some competitors
- Pricier than entry-level helmets
- Adjusting headgear might take some trial and error
As for the price—yes, it’s an investment. But when you’re staring at your weld for hours a day, eye protection and visibility should be non-negotiable. You’ll find cheaper helmets, but they often fall short in optical clarity and durability. For what it offers, the 3350 delivers excellent value.
What to Know Before Buying the Lincoln VIKING 3350
- Weight Consideration: At 1.41 lbs, it’s not heavy, but lighter helmets exist. If neck strain is a concern, balance is key.
- Fit Adjustment: While the X6 Headgear is praised, dialing it in takes a few tweaks.
- Storage and Maintenance: Comes with extra lenses and a bag, so keeping it clean and ready is easy.
- Battery & Power: It auto-powers on/off and includes a long-lasting lithium battery—super convenient.
- Grind Mode Access: The external control dial is easy to use, but make sure you’re not accidentally in grind mode when striking an arc.
Best Features of the Lincoln VIKING 3350
1. 4C Lens Technology
This isn’t just marketing fluff. The 4C Lens brings true-to-life color visibility and eliminates that old greenish tint. It dramatically reduces eye strain and improves weld accuracy.

4. X6 Headgear System
This comfort system balances the helmet weight evenly, reduces pressure points, and fits like a glove.
5. External Grind Button
No more flipping the helmet or fumbling inside—just tap the side dial and switch between modes.
