Throw some gas on that thing and you'll thank yourself later.
Nothing against taking a class if you enjoy classroom learning but you could save the money and put it towards a welder, read the manual and watch some youtube(there is a ton of info on there.) A lot of steel yards have scrap pieces for cheap that you can use to learn on. For anyone handy welding isn't some out of reach skill, you really just need to pick up a few basics than the rest is experience. It may not be pretty at first but if you're penetrating than who cares...
I'm absolutely a child. I'm so sorry.
