A couple good habits to get into right now while you are just starting out.
When you get ready to start welding, strike the arc 3/4-inch ahead of where you want to start your weld, drag the rod back to the start location. Make sure you stay with in the weld zone! This will allow the rod to be hot and ready to go by the time you get to the start location. I know the PA-200 has hot start, but it could be hotter! This is a very good technique to learn, and make a habit of.
Another thing, when getting ready to terminate your weld, change the rod angle more to 90-degrees, or maybe even 5-degrees the opposite direction, and back track 1/2-inch. This will help fill the crater, which is the weakest spot of the weld.
