With the Airco turned on, simply ideling, current went up to about 22
amps per leg, and here is the funny part...at 25 volts, burning .45
DualSheild, with 150 amps indicated on the welder, total current draw
only went up to 28 amps, raising the voltage to its top 35 volts...far
far into the OH **** spray transfer mode, only raised the total amps
to 35 with an indicated 250 amps of weld current. Chuckle..burning
that hot was like using a spray gun, the weld looked like it was
composed of nothing but tiny ball bearings, and had absolutly no
simularity to a weld at all. It was a sponge.

I'm not sure what you're describing here. A sponge sounds like porosity. In
regular spray transfer without Dual Shield, the weld looks like nice, shiny,
molten metal- kind of like the stuff the cop was made out of in Terminator.
You can put a lot of metal on fast which can lead to gorilla welds if you're
not careful.

It layed out a bead of metal that looks nothing more than tiny ball
bearings all piled up. I had the wire screaming through the nozzel at
35 volts. About 10' a second..chuckle..anything slower with that size
wire and it would burn back in a heart beat.

When I had enough fun with that, I turned it back down to normal and
made some of the nicest beads with good penetration Ive ever done
(which aint saying all that much..sigh)

I burned up all the .035 copper coated that I had in that mad minute,
and I had to stick on a roll of .035 dual shield...70s-3 IRRC.
Now I got to brush off the flux..sigh.
