@paul.waern - Typically when we hit the ball fat (or thin) it is indicative of a low point that is shifting backwards during the swing, and this is usually the result of not getting enough weight into the lead side. We start with our weight forward (55/45 on the front side; 60/40 for the longer clubs), increase that same weight forward to the top of the backswing (70/30), and further increase the forward weight during the downswing from halfway down (80/20) through impact (90/10) and to the finish at 95/5 forward.
Please spend some time learning and properly executing the 90% Weight Forward/Arms Straight Drill. Even though it's in the anti-slicing section, this drill's application spans a wide variety of issues, most definitely including the type that you are experiencing. This should get you on the path towards consistently crispy contact!
