Advice on buying my first MIG welder

i agree go with a 110 volt miller with .030 flux core wire will work well to 1/16 thick with proper weld prep

no it is junk parts will be hard to get
spent the $ http://store.cyberweld.com/millermatic135.html you get what you pay for
this is one i use all the time

the choice is yours i can understand budget being tight but you will kick your self for getting junk
The welder is gonna be used on cars and little around the house jobs and for building mini bikes and go karts. Not too expensive also. I want one that will deliver nice strong welds.
600$ is not much for a quietly welder

ok here is my .02
gas shielding is great when you have no wind ie in a shop of some sort
flux core burns hotter you can use it out side wind will not harm the weld process
but remember you have to reverse the weld polarity on the welder to run flux core
