Spray question

[brainfarth]

We have a new 304xmt with a 22a feeder running .045 wire and 98/2 for gas. The spray runs pretty good at around 25.8 volts and #4 on the wire. I was in a bit of a hurry this weekend to get a job out the door so I cranked it up to 33.3 and #7 on the dial and really had to watch my angle of approach, but other than that, it welded pretty smooth.
Here is where my question lies: Running with so much heat, does it change the metallurgy enough to compromise the weld integrity?

Kind of depends on the thickness of material and material type. You don't want to run it so fast and hot that embrittlement or undercutting occurs at the heat zone or toes of the weld.
