Just bought myself a brand new welder and it goes right down to 15amps so bodywork should no longer be a chore! Got one of the with the extra spot weld timer fitted. http://www.weldequip.com/portamig-mig-welders.htm Need to sell my other stuff now.
Good choice, would be mine too if money was no one object Enjoy! They are very well supported on the mig welding forum as I'm sure you know...
