for bodywork you need a machine with a minimum as low as 30amp, preferably lower, might be ok if you only weld 2-3mm, but I suspect not.
there are far better machines out there, ok more money new, but its not all about a cheap price, you want it to be easy to use and reliable, especially so if your new to welding.
you would be better off looking at the clarke range from machine mart but avoid gasless if you plan to weld cars or thin plate you will pay more but it will be a better machine and spares are available
