My shop is wired with a whole bunch of 6-50r plugs around the walls running 220v AC. I just picked up a dust collector with a 6-20p plug on the end. I believe it is rated to pull 13 amps at 220v Single Phase AC.
In a perfect world I would be able to use all of the 6-50r receptacles for both the welder or dust collector.
With that in mind, is this sort of adapter with a breaker on it up to code?

The "specifications" section says "safety listing - not listed" and the device label is distinctly lacking any official mark from ETL, UL, CUL or CSA. There's a difference between "claiming it meets" and "actually being tested and listed" and they hope you don't notice that.
Doesn't have this official mark, which it surely would if the alleged CSA certification was done by CSA, not random third parties:
Also missing the UL mark, but they only claim "conforms to" not certified or listed for that. Weasel wording of the finest order.
The sort of device can be fine. That particular instance of it - not fine.
Seems odd for a brick and mortar store, but perhaps Lowes has piled on the "list direct import stuff that's not sold in stores and not really sold or imported by Lowes" train.
Given that a 6-20 is not going to be a mass-market adapter, you might consider putting a small subpanel on the dust collector body with a two-pole 20A breaker in it - build your own from known good parts.
Ecnerwal's advice is generally correct. But the key issue, aside from actual certification, is whether the cord includes a fuse or breaker. According to the description, it does include a breaker. Without that breaker, this would be trash. It has the breaker and the description actually says "The Breaker is Designed to Trip Power when Drawing More than 20 Amps" so the next step is to go to the AC Works company web site. They are a US company, which is a good thing when it comes to electrical product safety.
A bit of searching on the AC Works site shows that some of their products are UL or ETL listed. My hunch is that they have so many different products that they decided to not bother with getting full testing/listing for each one due to the costs involved.
Home Depot has the same product available which is another good sign.
So while I agree with Ecnerwal that you have to be extremely careful with these types of things, in this particular case I think the product is legitimate and reasonably safe to use.
But definitely do not get this type of thing from Amazon or other online stores that drop-ship from other places ("Ships from Amazon" but "Sold by some random other company").
