An affordable starting point would be the Lidl gasless MIG welder. About £100, plus a decent auto face shield, gloves and other PPE.
The welder has only one control, and is point and squirt, and as easy as it gets for a starter.
Aside from my TIG welder, it is my 'go to' set up as it is simple, and works.
I sent @wokstation one a while ago to get him started.
