If someone is interested in such a cleanig laser for restoration projects as a backpack version (220 Volts or rechargable batterie packs for a working time of 2 hours), just let me know.
I have one to sell. Build in Germany.
Just used approx 800 hours and with full 20 Wats output and perfect condition..
Brand new price was 60k and I give it away WAY less (under 10k)!
As in the Video above for rust removal, all sorts of black coatings, coplete mold and spores removale, soot/smoke etc. etc.
Can be switched from 2 - 20 wats, so for any kind of carefull restoration projects up to car/old timer restoration!
No water coolling needed like on the old and very heavy systems!
