Economical stick welders are the go-to welding machines for home shops, farm and outdoor maintenance, and hobbyist. The coated rods eliminate the need for shielding gas, allow welders to work in windy conditions, and create secure welds on less than pristine metal. MIG welding is one of the simplest and most commonly used welding processes, with the relatively low cost and versatility making it especially appealing for small businesses. One way to lower the costs even further is by buying a used MIG welder. TIG welding uses a Tungsten electrode to create a precise weld with a clean and finished appearance.
