In some industries, a certain look is expected for MIG welds. For example, the motorsports industries has adopted the "MIG like TIG" look.
It involves using settings different from what is normally used for production. Wire speed in particular is usually much lower, which lowers the overall travel speed.
MIG welding uphill requires lower settings. A pro tip is to just use the chart or auto settings for thinner metal ( 2 thicknesses usually works well).
MIG welding thin wall square tubing in a common fixed position.
Weld sequence can help prevent distortion.
