Here is a table I copied from Esabs Website (With Permission) http://www.weldinginspectionsvcs.com/gmawdataCS.htm for GMAW Data.

Esab has a very extensive list of welding parameters for all of their filler metals at http://www.esabna.com/main.cfm?category=03&pageId=../html/products.cfm&category_desc=Products but you have to go through a few steps to get there.

Also check out out Ed Craigs site at http://www.weldreality.com/MIG_flux_core_data.htm

Hope this helps

Have a good day

Just a suggestion. I would contact the wire manufacture and they should be able to supply you with that data. I also believe that gas type will make a difference. If it is really critical to know this info then maybe do a DOE (design of experiment). A fast and easy way to find out these transition points is to first determine how much volume of wire that you are going to need then set it there and run a few beads while having someone ramp up the voltage then note the points where the transition took place. There is a minimum transition current at which below that point you will not achieve a true spray transfer. I have found the globular range for my application to be quite narrow. I have an axis that I set up which allowed me to do it by myself. Mikes info looks pretty good but if you want to pin point it then its going to take alittle work.

hope this helps

Yes, I am supposed to do Design of experiments using Taguchi methods
So I need these amp-Volt range for synergic MIG_MAG machine with the shielding gas 80%Ar+20%CO2
