Most of the stick welders come pre-installed. If it doesn't, setting it up shouldn't take much time. You just have to put the electrode at a proper angle closer to the joint. Then, the electrode's tip will move 15 degrees towards the joint. Move it 15 degrees upwards if you're welding vertically. You'll find 2 sockets on your stick welder. One is for the ground clamp, and one is for the electrode holder. Install both of them in their respective sockets. Tighten them as you need, and your welder is ready! You'll find plenty of tutorials on YouTube on how to set up a stick welder. Follow those videos if you still need help.
