Welding woes...frustrating!!

I'm considering buying a better welder I like this little welder for small stuff it has helped alot on small projects like fixing my lawn mower deck welding washers to remove my lca bushings etc but it doesnt seem to like to run a bead longer than an inch or so my puddle just disappears. The reason I didn't get a bigger one to start with is I dont have a 220 hook up at my house I'm considering getting a generator then I can run 220 with it.

I had a Miller-matic 110 unit I used to weld my Roll Cage in my Bracket Racer. It worked very well. I can't remember model number but it cost about $800 in the mid 90's.As stated the difference between solid core and flux core is day and night. I tried to find a you tube video but most of those guys can't weld for ****.
