It is very light weight and portable. Shuangbing is going to be a big problem for the red and blue. This will do very nicely for my home welding/assembly projects. I would not say it is a big deal, I can make pretty welds. The Shuangbing does not have dual gas inputs.
Shuangbing Features & Specs

Great product I need about three more. The portability is outstanding. Liked the diversity of metal it can weld. Had the Shuangbing assembled in no time. I was using these, and the 1/8th rods, in a 240 welder.
