Production guidance

This TUNGSTEN CARBIDE - Fiber Mark metal record pairs 100% power with 400 mm/s on Fiber 50W+, using 1 pass, 25 kHz, 0.02 mm hatch spacing, and 200 ns pulse width. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. Surface mark on tungsten carbide tooling. Extremely hard material. Source: rmlaser.us (2024).
2. 2. Treat this as an unverified baseline, not a production preset. A VERIFIED Parameters Library record requires three independent community vouches; an attached proof-burn image provides additional evidence.
3. 3. Bare metal is unforgiving of focus error: re-zero on the actual work surface rather than the bed, and wipe oils off before marking or the mark will read blotchy.
4. 4. MOPA pulse width is the parameter doing the work here — if the result drifts, adjust pulse width before touching power or speed.
5. 5. This runs at effectively full power, so there is no headroom left to push. If the mark is weak, slow the speed or add a pass rather than raising power.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this TUNGSTEN CARBIDE - Fiber Mark recipe is: “Surface mark on tungsten carbide tooling. Extremely hard material. Source: rmlaser.us (2024).” The source data was reviewed 2026-08-09; no independent vouch or proof-burn image is attached. Label the scrap test with the adjusted values and keep the accepted result with the production job.
