The filler metal supplier can provide you the appropriate parameters, most on line. You should also invest in an amp/volt meter. Perhaps you should invest in a consultant to get your shop in compliance with what is required.

Your best bet is to thouroughly read Ed Craig's welding site -

If your SMAW work was on material thicker than 3/16 inch than GMAW may not be a good choice for vertical up welds.

But do not dispair.... That same GMAW power source can do amazing things with gas shielded FCAW wire!

You really would benefit from the above advice to hire a consultant who really understands welding processes to get your program started and to get you well educated on the various processes that are available and where each one is best and $$$most profitably$$$ applied.... The money invested in consultants will be returned thousands of times in the first year if you are manufacturing even a medium quantity of product. Be humble, take the advice from a reputable consultant and you will be a very happy man.
