Protective Lenses

Find parts for my machine ↗

Compare protective windows for handheld laser welding equipment. A protective window shields the optics; it is a separate replacement from a focus lens.

Match the original part number, diameter, thickness, coating, rated wavelength and holder. Check whether the listing contains a bare window, cartridge or multi-pack, and confirm the installed welding head on the product page.

Know what you are ordering.

Protective windows shield the optical path from contamination. Match diameter, thickness, coating, wavelength and the original holder. A bare window is different from a complete cartridge.

Which specifications need to match?

For optics, compare diameter, thickness, coating, wavelength rating and focal length where applicable. For nozzles and wire tips, compare the mounting interface, geometry, wire diameter and rated process. A cartridge and a loose lens are different replacement formats.

Does a machine listing guarantee fit?

No. A listing identifies a model association and its stated configuration requirements. It does not certify every head revision or a third-party replacement. Check your original part and machine manual before ordering.

Can I order laser welding parts in the United States?

Laser Weld Depot sells laser welding consumables from its own inventory. Check each product page for availability. Sold-out items cannot be ordered. Shipping charges and available services appear at checkout for in-stock items.
