  • Looks like dude in the orange saw dude proposing and often times proposals come with a fancy expensive ring. Clearly an easy mark. As the orange guy walks up, you can see him pull mace out of his pocket which he then sprays in dudes face at a close range. However, instead of being incapacitated, proposal dude clearly has a strong paradoxical reaction to the mace and becomes the pure embodiment of rage in physical form. This proves to be problematic to the man in orange.


  • Oh yeah that’s a pretty solid benefit right there. I swear the oddest things will block them from cutting. I didn’t even consider the smoke diffusing the beam.

    Like the most powerful laser I’ve used won’t cut through a paper sticker or even the residue but it’ll cut through .75" steel like it’s nothing.

    The optics is a big deal too. On the big ones everything is pretty reasonably sized and they’re still a pain to clean. I can’t imagine what it’s like with those tiny ones. Also, those larger lasers lenses are really commonly coated in thorium and a speck gets on there it’s going to superheat and vaporize a lot of the lense. Pretty damn dangerous to be around lol!


  • CNC laser operator here.

    I don’t know about these lower power lasers so I may be wrong. With the lasers I’ve used (200-2000W), the air/oxygen is used to create a superheated jacket of gas around the laser which allows it to cut a nice smooth edge. It also has the added benefit of blowing away the slag/dross that’s created.

    When we cut more temperature sensitive materials like aluminum and stainless we use nitrogen, which cools the material. This creates a pretty jagged deal with the dross that you gotta sand off but it prevents blowouts and really creates a nice edge if you get the pressure dialed in just right.
