Just to make a suggestion.....add a good quality auto-darkening helmet and you'll be a lot quicker to master the art. My $100.00 helmet has a fixed static lens setting of 11.....and I'd suggest getting one that was variable with a max of 10. On low amperage stuff you will be able to see and control your feed better. I've even seen a LED light that clamps onto the gun to give you better visibility at lower amperage settings. No shadows...makes sense.
