Hello David, are you sure that you want to go with globular transfer? By switching gases you could likely go with spray transfer and end up with welds that are sound and the operator appeal will be much greater as well. Globular transfer will yield a much higher amount of spatter and irregularity of bead profiles, getting into the spray mode of transfer will likely increase travel speeds, provide sound weld bead fusion and yield a better aesthetic result. Is there something special about your product that requires you to consider globular as the answer? Maybe providing a bit more overall information might help with suggestions. Best regards, Allan

A bit more information would help, like if position, thickness and joint configuration. To answer your question as fully as can be answered in its present form, yes, you can most definitely produce globular transfer with .035 and ArCo2. Somewhere between 22 and 23 volts on our equipment (Miller 452's) transfer changes from short circuiting to globular and remains that way as we use the same gas mix you do. As the other poster pointed out, if you want to spray, you need a gas mixture with 80% or better Argon content. A really good site for mig/fcaw is http://www.weldreality.com/ . Ed Craig does a lot of self promotion and promotes his merchandise heavily, but there is a lot of good information for the browsing there. The limitation of spray is that it doesn't work well except in downhand or horizontal fillet, and personally I wouldn't use it on something less than 1/4" thick as its much hotter than GMAW-S or GMAW-G even with relatively small wire such as 0.035.
