Welcome!
Metal etching generally uses a removable coating that is designed to absorb a specific laser wavelength and convert it in to heat to be delivered to the metal substrate to be etched. Metals tend to reflect laser beams and not absorb them. You can overcome the reflectance with a high enough intensity, but you are looking in to multi-kilowatt CO2 systems for CW or q-switched multi-joule systems for pulsed applications. Neither tend to be hobbyist friendly. You can etch thin metal with a properly focused 15W CO2 laser and the right coating.

Welcome to the Forum. :san:
The "Get Some Goggles Now" thread should get you straightened out.
Basically, on a budget, go with the Uvex SCT Orange goggles. They are infinitely better than nothing.
As an intermediate option, Eagle Pair from Survival Lasers are excellent.
The best option though, is to get certified goggles. Personally I use the ARG goggles from OEM Laser Systems.
