Applications & Use Cases

Routine changes
Replace the window when it shows spatter, pitting or burn marks. A dirty window absorbs power and can crack.

Protecting the focusing lens
The window keeps spatter and fume off the focusing lens above it.

Loss of cutting power
If piercing slows or the kerf widens, check the protective window before changing cutting parameters.

Frequently Asked Questions

How do I know this is the right window?

Check the part number on the old window's packaging or your parts list, or measure the diameter and thickness. They must match the size shown.

Is it a genuine part?

No. It is an aftermarket window made to the same size. The OEM part number is shown so you can match the window you are replacing.

1 pack, 5 pack or 10 pack?

It is the same window in each. The 10 pack has the lowest price per window.

How should I handle it?

Hold it by the edge with clean gloves and keep it in its case until fitting. Clean only with lens tissue and optical alcohol.
