Another thing to consider is your wire size. Here, one can use; .023/.025" .030", .035" and .045" in a MIG for common sizes. That equates to about .5MM, .7MM, .8MM and 1.1MM. I have a 120V machine that has .023" for exhaust tubing, sheet metal, etc. and a 220V machine I've found that .030" wire works best for the automotive related welding I do. Wire size will make a huge difference in your power and wire feed settings. Experienced welders can cheat either way but a novice needs to get close on the wire size. Maybe that's why I have two makes me look better.
