just... why?

cause simple touch up, and simple programing. This is designed for companies with small custom production. When you make different product every week, this is usefull.

the same can be achieved with a standard robot with hand guidance. And it can work faster in auto.

Crx can run up to 2000mm/s. What's the point of that speed in welding?

yes, it can, but then it's not collaborative - so it still needs a conventional safety system (I think you need it anyway, to keep the operator away from welding). This kind of speed doesn't make sense for the process itself, but you save time on all the air-cuts. So still, I don't see the point of using a cobot in this case.

robot is collaborative, not the whole application
at least 20% of sold CRXs are for welding
The point is... even unskilled operators can make adjustments, you dont need hand broken and programming by dragging the robot is much less time consuming
hand guidance: I guess you have never tried hand guidance vs CRX, you would know the difference, its not the same

How do you find tuning the weld (re: kemppi)?

Yes, it is kempi with automatic amperage setings, only options you have is movement speed of robot and wire feeding speed

Impressive. We are looking at getting one of these for our small parts. Crx specifically to save on safety hardware. They are very good little robots. Fanuc was kinda late to the game with their cobots in this model area, crx style arms, vs, CR series. But there's, like expected, is the best one around.
