Can you run a 240v US split phase welder on 230v UK single phase

I am moving from the US to the UK and would like to know if my welder will work on UK power. The welder is 240V 50/60 hz so that should be fine as I understand it… except, the welder is wired for US split phase so it has 4 wires (L1,L2,N,G) whereas UK power is 230V with only 3 wires (L,N,G) true single phase. Assuming I am correct so far, is there a reasonable way to run a 4 wire 240V split phase appliance on 3 wire, single phase 230V power?

EDIT: Thanks @Three for spurring me to actually open up the welder as it has completely changed my question. I had just (stupidly) assumed the 240V was 4 wire. The welder is wired (as is the receptacle) for 3 wire 240V. So the new (hopefully more accurate) question is-

My welder is wired for L1,L2,G 240V whereas the UK supply is L,N,G 230V. Is there a reasonable way to run or rewire to run a L1,L2,G 240V appliance on L,N,G 230V power?
