Not really. The easiest way for me to tell you goes like this:
Listen to the welding. If it goes buzz...buzz...buzz (like intermittent arcing) adjust the speed slightly and try again. When playing with wire speed, you want to get a constant gradual buzz.
Different wire (flux or mig) comes in different sizes. Depending on the voltage of the welder and the size/type of wire being used, you will have to make slight adjustments to wire speed. Most often my welder's wire speed is somewhere between 4 & 6 (but remember, welders aren't the same, materials aren't the same and the temps as well as conditions in your area can differ from the next guy).
If you are using a 110v mig welder, make sure you are using wire size .023 - If I recall, harbor freight doesn't sell that small of wire but it works much better with the smaller welders.
