You have it so they use it, but single phase will run it all just fine. The pool pump and welder can benefit from 3 phase, but for the pool pump the benefit is marginal. For the welder a modern inverter welder is better yet.

We can get 400v 3phase inverter welders here.

Yes, we have it so we use it - for sure.

The pool pump on 3 phases seems slightly more efficient when I compared them last time. The pool is also being fitted with a heat pump inverter, which doesn’t need 3 phase.
