   Makes me wish there was a thumbs up button.  I appreciate you providing   
   alternatives to welders most of us can't afford.   
      
   You may under evaluate the garden shed welder a little though.  A lot of   
   us are running a little more than that.  Most guys who are half serious   
   garden shed (more likely carriage house(garage)) welders are running a   
   200-250 amp machine off a 230V 50 amp dryer outlet, or they have   
   installed a larger breaker just for their welding machine.  My Miller   
   212 says it really should be on 60 amp circuit, but I have it on a 50,   
   because it was convenient. Most of my welders can plug into the same   
   outlet.   
      
   Sure there are plenty of little 150/180 amp machines out there for light   
   gage work (I have one of those as well), but there are plenty of home   
   shop guys running a little more than that.   
      
   While I won't do anything but proper setup on the welding table to do it   
   with the 212 in straight MIG welding the application table says it will   
   run 3/8 mild steel.  I won't show my welds because my fragile ego   
   couldn't take the criticism, but I've welded 1/4 and 3/8 wall box tube   
   to solid steel round bar.  The convenience hitch (moves my gooseneck and   
   tow trailers around the property) I use on the back off the little   
   tractor (snaps into the quick hitch) is made with such welds.  I   
   wouldn't have made it outdoors or in vertical or overhead positions, but   
   it has stood the test of time.   
      
   If I have to weld outdoors and in awkward positions I tend to run flux   
   core gasless wire instead.  That's what I keep in the little WeldMark   
   (Hobart) machine.   
      
   My first (arc) welder was a little Lincoln tombstone that I struggled   
   with.  I have since learned it was likely as much the machine as it was   
   me, but I still tend to shy away from stick, even though I now have   
   decent 200 amp AC/DC machine (my TIG power supply) that should run it   
   better than that old AC cracker box.
