Not sure.  Mig if I can affored it, otherwise arc.  Is it worth paying extra for the gas flow? 
  
I see that there are comparatively few 110 welders on the market compared to 220.  My barn is wired for 110, but I have been thinking about putting in a 220 outlet or two.  But, my shed where I do a lot of work is only 110.  Is it that much of a disadvantage having a 110 welder? 
  
 
Yeah, I have one near where I work.  Do you think they are any good? 
  
  
What do you think I should get in the $400 - $600 range? 
  
Say my typical use is to weld a patch onto a 48" deck.  What would I need?
