I have a lincoln (sparkeler) 110 volt and its cute at best give it a good once over.....the amp adjustment knob broke on the first day but it has always worked to my satifaction for the small things i have used it for.
I have an SP 175+ and it is no fun trying to weld aluminum with. The power mig 180C and 180T are set up to run a spool gun. The SP 175 and 135's are not. There a couple of websites you can find these on. E-bay and weldingmart.com are two that come to mind. If you still are wanting a SP 175+, mine is for sale with everything that came with it brand new. And the aluminum welding issues are why. Chris
