Auto-Darkening Filters

Improving upon what the welder sees.

Your goal is to weld consistently great welds. Our goal is to provide you with eye and face protection and also improved welding filter optics for better clarity.


How auto-darkening filters work.

Always read and follow all user instructions.

  • The view before a weld through an auto-darkening filter.
    Before

    With the helmet in the safe down position, you have a clear view through the welding filter. Both of your hands are free and the electrode can be precisely positioned.

  • The darkened view during a weld, seen through an auto-darkening filter.
    During

    Within a millisecond of the arc strike, the filter has switched to the dark state.

  • The view after a weld through an auto-darkening filter.
    After

    The filter automatically returns to the clear state after welding is complete, allowing your immediate inspection of the weld pool, and preparation for the next weld.

Imagine what more realistic-looking colours and details could do for you:

  • Provide better control of your weld puddle—with a view that appears lighter, brighter, and more realistic
  • Help you focus on your welding set-up, welding technique, and inspection of just-completed welds
  • Give you a clearer view of coloured welding machine controls—even with your helmet in the safe, down position

Which colour tone works best for you?

Work with an even better view and control of your weld puddle. With the new 3M™ Speedglas™ Variable Colour Technology, you can choose between natural (A), cool (B) or warm (C) tones for your dark state. You determine which colour tone provides the best viewing contrast for your welds, and the most comfort for your eyes.

How to choose a welding filter.

 

  • Work with an even better view and control of your weld puddle. With the new 3M™ Speedglas™ Variable Colour Technology (G5-01VC), you can choose between natural, cool or warm tones for your dark state. You determine which colour tone provides the best viewing contrast for your welds, and the most comfort for your eyes.

  • If yes, you have plenty of models to pick from: all our auto-darkening filters have variable (selectable) dark shades.

  • This is a key decision factor. You might want to also consider your needs for specific dark shade levels, light-to-dark switching sensitivity, and dark-to-light delay options which are features that vary from model to model.

    Recommended shade numbers according to ANSI Z49.1:2012

  • For many welders, the ability to see more of their workpiece without moving their helmet or head is very important. For these “big picture” people, the G5-01, G5-01VC, 9100XX, or 9100XXi models will be most appropriate.

  • Then our tack welding comfort mode may be for you. The comfort mode setting may help reduce eye fatigue caused by your eye constantly adjusting to differing light levels during tack welding. It's available on G5-01, 9100XX, and 9100X filters.
