    Plastic lenses are not well suited for welding even if CR39 lenses get less pittet than mineral glass lenses.

    The protection against the UV and IR emissions are generally NOT good enough.

    Get # 5 or $6 dark green lenses in glass. They will absorb the necessary emission and protect properly

    Welders tell me they use a stock #10 filter. It is very dark. Under normal conditions, you can't see through it.

    I use an auto-darking welding helmut, it makes your welds twice as good.

    On the helmet my father used to have the plastic was used as a shield for the glass lenses that were beneath it. It worked quite well. The helmet came with at least 5 different densities of lenses.
    You could interchange the lenses to form what ever density you needed for what ever job you needed them for. It was a nice little system.

    #5 shade welding lenses come in a varity of colors. The shade refers to the darkness of the lense. A #5 lense being a much lighter shade than a #12 lense,
    meaning you can see through a #5 lense easier than the #12. This is very important, you should not weld with a lense that is not the right "shade" for the type of welding you are doing. For example if you welded 1/2" plate steel together with flux core wire or solid wire in the pulse mode, using a #5 lense you could receive severe eye damage. A #5 lense is suitable for flame cutting, brazing and some plasma cutting, but not recommended for most welding. If you are not sure and you are planning on doing some welding, ask you local welding supply store for the correct lense for the type of welding you are going to be doing.
