Ok guys, I'm in need of guidance. I'm trying to dial my MM252 in better for spray and what I'm coming up with is waaaaay off from Hobart's HB-28 spec sheet's parameters.
Hobart recommends:
5/16" Material
.035 HB-28
25-26 volts
420-510 ipm
90/10 (C10)
I'm coming up with:
5/16" Material
.035 HB-28
27 volts
550 ipm
85/15 (C15)
35 cfh
My spatter levels are more than expected with spray and I'm not getting the smooth hiss/crackle. I'm getting a raspy sound. The molten droplets ARE smaller than the wire diameter and the bead looks good but, I would say what I'm getting is just North of globular. I realize that more CO2 would make my voltage setting increase a bit but, this is not the spray I was used to when I was in industry. We were using Dimension 652's and power was never a problem. Any suggestions would be appreciated.
If I use Hobart's parameters, I am definately squirting globular.
