Welding Helmet Lens Cover

Welding Helmet Lens Cover

Description

WeeTect welding lens cover (WWLC) is a welding helmet lens cover which cut from optical class polycarbonate sheet. Compare with other welding helmet replacement lens, WeeTect welding lens cover (WWLC) has more visibility, smooth edge and competitive price.

The quality control points of the clear welding lens are polycarbonate sheet itself, processing selection, deburr technology and packaging. Most of other clear welding lenses manufacturers will use poor quality polycarbonate sheets and punching process which are easy to cause spots and scratch on the surface. WeeTect welding lens cover (WWLC) uses optical class polycarbonate sheet from our sister company with very competitive cost. And we use CNC machine cut to size to secure the good surface and smooth edge.

WeeTect Welding Lens Cover (WWLC) is a perfect candidate for all kinds of welding helmet manufacturers, brands and distributors. The sustainable performance could prolong the longevity and protect users consistently

Advantages of WeeTect Welding Lens Cover :

  • Better visibility
  • Smoother edge
  • Clearer surface with mask protection
  • More competitive price
  • More flexible size options
  • Special surface treatment as options
