Hey Larry if you don't use a spool gun you want to close the gap up if you can right after the rolls and use a teflon liner in your torch cable. Your welding chart will tell you where to start on flow. You don't mention the thickness of what you're welding. I would try about what you had 25 - 30 cf/h. Also keep the torch away from the puddle about 3/4". Let us know how it works for you, we like pictures ;-)
