"Another issue will be a cylinder for the Argon/CO2 shielding gas.... Local shop wants well over $200 for tank filled
I see on line empty tanks for as low as about $60.00....To fill locally will be $30.00. Found this e-store that ships filled tanks (don't think the tanks are new) for $89+Shipping comes to about $104 total"
I'll go against the trend here and recommend getting to know your local welding store. Most places I've dealt with, once they know you are serious, will deal on a welder. I've bought two machines from my local store and both times they met or beat the prices on the internet and they will save your butt when you have issues and many are open saturdays. Also, when you need to refill your tank, and you will run out when you need it most, the shop doesn't actually refill "your" tank, they exchange it for another tank of the same size. If your tank is not from their shop or gas suppliers chain, they charge you a testing fee (at least they do here in CA) for pressure testing the cylinder which will just about negate any savings from buying online.
Another avenue would be buying a used name brand welder, especially right now that people are hurting for money, you could save some big bucks that way.
If you are thinking of getting a machine with more capacity, make sure you have the current to run it. Depending on your house/garage, if you don't have dedicated 220V service, most electric clothes dryer plugs are limited to about 20-30 amps. You can run up to about a 200 amp mig on this much current.
