I had a look awhile back and the financials were not attractive. From memory, I believe they have company options available.

Their welding as a service (WaaS) revenue model is interesting; I believe they loan out the equipment & charge by meter welded (but double check this as I could be incorrect). Be mindful of your circle of competence with this one. Their machine, while incredibly fast & efficient, can only weld certain styles and this is probably where you'd need to figure out if the addressable market for this particular style of welding is attractive or not & if there's product market fit.
