I am not a professional welder but I've welded for about 20 years. I did have a job for some years that entailed some fabrication. I've had some tig lessons from the miller rep.. The welder and spoolgun set up I have for home is around $2000. I have a Hobart ironman 230 with a spoolgun for aluminum. Your going to invest at least $500 to $1000 to pick up a decent mig to weld aluminum. I would say anyone can do it it just takes practice. I started with a $299 110 Lincoln.
