Globular Transfer

admin

As I understand it, Globular Transfer will result in higher penetration than Short Circuit.Will Globular Transfer be possible on my MM 252 using C 25 gas?  What are some suggested voltage and wire speed settings?  Have any of you guys done this?Thanks,Jack
Reply:I have ran globular and spray transfer with the MM252. It takes some adjustment to get it just right. Are you running hard wire or metal core? I cant remember the properties of C25, I do know you need a mixed gas to achieve globular and spray.
Reply:Im thinking C25 can do globularThe Praxair® StarGold™ C-25 gas blend (75% Argon/25% CO2) versatile mixtures for MIG welding of carbon and coated steels, providing good weld penetration and bead wetting characteristics.
Reply:I'm running hard wire.
Reply:It most likely will work. I cant remember off hand the wire and heat. I think it was around 28 volts and either 280 or 340 on the wire? Its been a while, I usually use metal core. .035 hard wire?
Reply:Globular transfer will start happening when you raise the voltage up around 23 volts.  The higher the voltage the more violent the arc.  With C25 you cannot go into spray transfer.  With C20 or less carbon dioxide you might get your machine to start spray around 26+ volts.
Reply:I was taught that I needed to know what globular transfer was so I could avoid it!  Basically just shy of spray (with solid wire), but nasty, with a high amount of spatter,  real hard to control, and pops and cracks a lot.  Not to smooth sound of properly adjusted short circuit transfer.  If using C25 (which will prevent you from going to spray regardless of voltage) you will run into globular if you run the voltage too high.  I personally don't like it, and generally run into it if I get aggressive with the voltage.  It's my signal to turn it down!!Tracker401
Reply:Co2 makes globular easier to  achieve.  .045 wire, 225 ipm and twenty some volts will get you globular.  It makes a bunch of spatter and a frikkiin mess.  But it is an acceptable weld.Each size wire gets to its own end.  .035 wire about 350 ipm, and .045 wire at over 200 both are in the 200 amp range  by then and globular is what you get.David HELLO lotechman  Good to see yaDAVID RLast edited by Fred Sanford; 01-17-2011 at 07:43 PM.
Reply:+1 on the Co2 and Co2 rich mixtures, older power supplies usually had a tap that made the volt amp curve droop more and welding that way was cheap.I wonder if what the OP is looking at is the newer migs having a C25 setting something like .035 wire, 450IPM, and 23 or so volts for 1/4" plate. Which makes for a pull the trigger and run with the gun type weld?Matt
Reply:A welding instructor I had once told us that there were three types of metal transfer for wire welding, Short circuit (holds up index finger), Spray (holds up ring finger only) and Globular (holds up only middle finger) Globular is bad, don't ever use it. (he says this while flipping all of us the bird). According to Ol' Don Apple globular is bad OK.
