A resistance welder is a special type of welding equipment that uses electrical heat for the welding process. The resistance welder passes a high electric current through the circuit and the electrical heat due to the circuits’ resistance melts the point of contacts. The electrode material holds the part for a certain time and welds the material. The time the electrode holds the piece and the current flow depends on the thickness of the wire.

Resistance welders come in various types such as spot welders, seam welders, flash welders and projection welders.

Some important parameters you must consider before you buy resistance welders are:

1. The size of the product for which you require the resistance welders
2. The number of pieces that you want to weld in a single operation
3. The quality of the weld
4. Dimensions of the weld
