Those sights will help you get in the 'box', but your still going to put a piece of scrap on the table and experiment with the settings to find the 'sweet spot'. I'll also add this: Check your electrical connection starting at the breaker box all the way up to the connections inside your welder. If your not comfortable working around electricity, hire somebody that is. Welders draw a lot of current and create heat and it is not uncommon for the heat cycles to cause loose connections. If your welds start out good and get more erratic as you go, this is a classic case of what I just described. Also check your ground clamp. It should be clean and not oxidized. Make sure your contact tip isn't worn. Once you get to this point, set up your scrap piece and play with ALL the settings. You will learn a lot on your own.
