I've found 4140 great to machine, gives beautiful finish, no tear out as you get with mild steel.
The link says you need to preheat to weld, I've never, use a low hydrogen rod as 7018 or mig. Will harden in the weld zone though if you need to machine after welding.
Free advice is worth exactly what you payed for it.
