Yep keep it.You might get sticker shock when you fill the Acetylene tank. Last one I did it was $135. Well worth to have around.In-dispensable to me
You might pick up one of those 110V little wire feed welders from Harbor Freight. ($100.) Without the cover gas , you get some splatter,but sure is handy along with the torch

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
