Once you have the gas/wire speed/heat setting dialed in and butted panels have small gap,it should come out like you want ,has worked for me. Obviously you will need correct size wire for thick/thin steel

Though there is a noticable difference between machines,you still should be able to manage to get a good weld. I've had a Miller for about 13-15 years of dependable service,it finally gave up and needed some sort of switch ,so I retired it and replaced it with my back up Lincoln welder ,which had better penetration,overall cleaner,smoother welds,but after couple months of use I decided to get Hobart because Lincoln kept acting up,wire kept slipping,getting stuck,I called independent repair shop and the tech told me to buy Miller or Hobart,because they very rarely come in for service,but always fix Lincolns, so I will never buy another Lincoln.
