I bought a multi function power supply a while ago, and use it for stick welding every once in a while.
Stick welding is great for pumping out a lot of power and thicker materials. The first project was adding some forklift forks to my tractor bucket. Those are big and thick, and quite a heat sink. Plus I wasn't sure of the temper, so I wouldn't want to make the whole things cherry red with a torch.
I'm good at blowing holes in just about anything!!! Lots of practice filling holes.
