.035 wire is too big for your machine I have 3 250 amp lincolns on my floor and unless we are doing structural steel we run .030
try using 5% helium 70% carbon dioxide 25% argon mix this will get more heat aout of your little machine mig isnt really accurate in this case since helium is not inert and will cause the wire to burn hotter.
heat is the problem trust me , a simple way to prove it is this: set the welder up as you were .start a bead slowly move your nozzle closer to the work ,does performance improve ? it should , think of the wire like a resistor longer resistor = more energy to melt it
also the bacon thing is kinda half right it should sound like bacon frying without the silences between it should be a sizzle with a slight little groan the more uniform the better , remember with welding usually if it looks good it is good
