If you have it then YA - if not then you do with what you have available.
if you are buying new - the variable heat models are not too much more I don't think. the Lincoln sp 135 is the low model in the 120 volt model. I beleive it was the replacement for my sp100. I have had it for 12 years and love it. They also make a compact bodied 220 volt model as well that can weld thicker steel as well.
