Glad you got it done.
I'll add a little something to the thread:
if you do plan on buying a welder for future projects, it's not going to be cheap. You can buy the smallest, cheapest, flux core wire feed machine and probably come out around the 100-200 mark. But that machine is going to be....well, just awful. And an "awful" machine just makes it that much harder to learn the process and your "outputs" never get to where you want it to be...quality wise that is.
Sometimes you can get lucky and find a good used machine going at a decent price, but that's always a "wait and see" game. Not great if you need something done right now.
You want, as a minimum, a MIG welder. Home depot sells a decent Lincoln 185 (what I have) for around 600 cdn when it's on sale. This will handle most home shop needs and is a pretty easy machine/process to use/learn. But you will need a bottle of 75/25 mix. The prices on that vary depending on where you buy it from. I had to buy my bottle, which was 500 bucks. Then 90 bucks for the fill. You can rent bottles here, but you need to pay a 500 deposit and then a monthly fee, all on top of the price of the gas.
Then you need consumables (wire, tips, etc) and protective gear (helmet, coat, gloves, etc).
You can get machines that run on 110 power, but they'realways pretty limited by the 15 amp circuit most home circuits run on. This limits the welder. I prefer 220 machines, but I have a 35Amp 220 plug in my garage. I specifically had it installed when we built the house because I knew I wanted 220 for welding. If you don't have one in the garage you need to have one run to use 220 power, unless you want to make a loooong extension cord to steal the oven or dryer 220 plug.
You're easily over a grand just to get a decent rig up and running and then you have to learn how to use it well.
100 bucks was not that bad a deal if all you had to do was a couple nuts and don't think you will need to weld much in the future.
What do I do when I need to get some welding done?
I've got a Lincoln 180 MIG, an Everlast 250Ex TIG/stick machine and a 50 amp manual plasma cutter. Somewhere around 5-6 grand in gear and bits, which is actually pretty cheap for the capabilities it gives me. But I work on my own cars (as well as freinds stuff) and such so they've paid for themselves a couple times over. Same as my old Atlas TH42 has paid for itself in getting my hobby projects done. I don't even want to think about how much I have sunk into that rig and tooling......
