The thing about welding is the machine is never big enough to do the projects that keep getting bigger and bigger
		
		
	 
This ^^ seems to sum up my experience.  I have a  LOTOS LTPDC2000D.  200A DC, yet the open start DC voltage has a hard time doing 1/8 7018.  Dang.  Need a bigger welder.  I was going to do little projects, repairs, then, huh, some of the monstrosities I'm coming up with.  It's fine, and doing fine, but now there is a new wish list.
To me, welding was a time consuming, trial and error, make some total junk, then make some better junk, then work on a simple project, read look and listen, practice some more --- then go for it.  There are known knowns, and known unknowns, then there are--.  Making a one off, from a cold start, right the first time, well designed and functional,  with a cheap low capacity (inverter) welder, not sure about any of that.  I have a Lincoln 225 ac/dc also.  That can get a lot of work done, just not my versatile go to unit.
