air engraving pen for sale, brand-new and used.

I have for sale my 160w upgraded CO2 Laser machine with autofocus attachment, 4 axis rotary chuck attachment, motorized z-axis, 3ft x 4ft working area, metal slat cut table and honey comb table. I bought this in November for $21,000 with all upgrades. Normally they come standard with 40w and you can only get these up to 100w.
