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.
