I know what you're saying but I have a good bit more wire speed and I get the same result with larger wire. I have .035 and .045 in both alloys and two brands. 5356 never got better than the far left weld, no matter the wire size, speed, volts or argon flow and I went through it meticulously. I was filling my shop with aluminum smoke over and over. I quit the spool gun before I damaged myself and tig welded my boat stringers with 5356 filler.
The 250p wire feed speed measures a little over 410ipm but Mark says you can't get an accurate reading that way due to the machine giving the wire feed more power when you start welding.
The wire speed display gives you a reference number to adjust by and switches to actual welding amps while welding.
