Okay thank you, i dont know of any welding supply shops locally off the top of my head. But im sure a quick google search or look in the yellowpages would yeild somthing local.
Around how much is a full refill usualy on a larger bottle? (i know this probably varies depending on area) but just to give me an idea. And its 75% argon, 25% CO2 correct?
Your gas mix is correct.
The Eastwood welder you are looking at is a Chinese copy of a Miller 175. Don't buy it. A used Miller 175, however, is perfect to get started with. The Miller 180 is the latest version of the same thing. I would look for used on Craigslist. Also,
Hobart is Miller's second label and great for the money.
The thing with Miller or Lincoln machines is that they use very standard/available consumables. The tips and similar parts are available everywhere. If you have a non-standard machine, finding the consumables is just one step more difficult. You don't need that hassle.
If you use flux core wire, no shielding gas is needed, but it is easier to weld with "solid" wire and shielding gas. I agree about buying the bottle, but seriously, do not sweat that, because in the end, you don't use that much gas. That isn't a major expense for a home welder. Most people get an 80 CF bottle and it lasts a long time. Like a whole spring over with power steering takes less than 1 bottle of gas. Don't get hung up on this.
I welded a lot of metal using a $50 auto dark helmet from Harbor Freight, but I have really enjoyed my $300 auto dark Miller helmet. Again, the domestic stuff is more expensive but it's also better and a good place to spend your money. Trust me that the welder itself is just the start, and you will need grinders, vice grips, protective clothing and a whole lot of other stuff that costs more than the welder itself. For instance, I would recommend you buy 3 angle grinders, one with a cutting wheel, one with a grinding wheel and one with a flap disc. That way you don't need to be constantly swapping out while you work.
One other thing to budget in. A heavy gauge extension cord for your welder is great to have, You can make it or buy it, but it makes it much easier to get the welder into position. Mine is 8ga and was about $80.
Spend some time shopping Craig's list if your budget is limited and you'll come up with what you need.
Good luck.
