Shielded metal arc welding (SMAW), informally known as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
This system of welding is great for outdoor and thick metal application. It is also the least expensive. If you are looking to get into welding on a budget this is the way to go.
Great for gate and fences, large or outdoor sculptural work. Or just getting some practice in controlling the puddle.
