Welding lens DIN 9 made of mineral glass (2 pieces)

The shade number, also called the DIN value, indicates how dark a lens is. The higher the number, the more light the filter blocks. A higher value therefore means a darker image. Always check that the lens suits the work you are doing and the recommendations of your mask's manufacturer.

What is mineral glass in a welding lens?

Mineral glass is a traditional material for welding lenses. It is hard and scratch-resistant, so your view stays clear, even after regular use in a workshop. With a well-maintained mask, you replace the lens when your view becomes noticeably worse or when it has cracks or damage.

Who is a DIN 9 welding lens intended for?

These lenses are intended for anyone who uses a welding mask or welding helmet and wants to replace the filter glass. That can be a professional welder, but also someone who does occasional welding. The shade number determines which type of work a lens is suitable for. Consult the user manual of your mask and the applicable safety regulations.

Checking size and compatibility

A welding lens must fit in your mask's holder. Therefore, measure the dimensions of your current lens or check the mask's manual before you order. A lens that is too small or too large does not fit properly and does not provide reliable protection. If you are unsure about the size, contact Proffix before you order.

Working safely with your mask

Always replace a damaged lens immediately and do not keep working with cracked glass. Preferably combine the filter glass with a clear cover lens, so the lens itself stays protected from spatter and dirt. This way the filter glass lasts longer.
