Wire feed on a MIG machine is controlling AMPERAGE -- while your other control is VOLTAGE... turning down the feed speed is turning down AMPERAGE. Welding is the combo of voltage and amperage.... So, of course, without being there and seeing what's happening etc - I'd bump the feed up rather than turning it down. Increasing the amperage will help you wet out the weld --- which is something I noticed right away.
Also -- after NOT welding for awhile (like hours/days) - the shielding gas can/does escape your MIG gun.... so before welding after not having welded for awhile - run 10" or wire and this will purge the gas.
Snipping the wire at a 45* angle will have the machine using the voltage on a smaller contact point - thus increasing the heat momentarily - it's a good trick on thin materials. Think of this like the tip of a spark plug and the 'gap' and size and shape of the electrode strap.
If you're still having issues -- I'd turn the VOLTAGE down before I'd turn the WFS (wire feed speed) down. But try to learn to weld with the parameters they say first. The machine is dumb - and you're smart - and you can make adjustments to yourself that the machine can't. LOL
