3M™ Speedglas™ 617830 G5-01 Auto-Darkening Welding Helmet Adlfo Kit

Adjust your welding helmet, not yourself

Based on extensive input from welders working at high amperages who need to grind frequently, the 3M™ Speedglas™ Heavy-Duty Welding Helmet G5-01 is created to be adaptable to an individual’s needs and situation.

Speedglas TrueView now with Variable Colour Technology

The 3M™ Speedglas™ Auto-Darkening Welding Lens G5-01VC offers 3M™ Speedglas™ TrueView Technology in the light state with your choice of colour tone in the dark state. Control how you view your weld.

Literally see the difference

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..

Choose how you see your weld

To provide better vision and more control of your weld puddle we now introduce 3M™ Speedglas™ Variable Colour Technology: choose between natural (A), cool (B) or warm (C) tones for your dark state.

A- Natural - Dark State 8 at variable colour level A

B- Cool - Dark State 8 at variable colour level B

C- Warm - Dark State 8 at variable colour level C

You determine which colour tone provides the best viewing contrast for your welds, and the most comfort for your eyes.
