Spot welding is done by a spot welder, and it is used to quickly and easily create a small weld using electric resistance. It has two electrodes that pinch two metal pieces together and apply current. The resistance between the metal pieces generates heat that creates a weld. Spot welding is generally done for thinner sheet metals, and can also be used for wire mesh. Thinner stock is easier to spot weld.
The Chicago Electric 45690 is a 240 volt spot welder that can weld up to 16 gauge steel. Learn how to use MADE’s spot welding machine in a welding class, learn more here!
