Portable spot weld

A portable spot welding machine or portable spot welder is a tool that is used for permanently fusing two or more metal sheets. By heating and using pressure on the welding spot, portable spot welding machines can permanently weld multiple metal layers.

The word“spot” in this welding method applies to the welding point where the pressure is applied and the heat is conducted.

Spot welding is generally known as resistance spot welding, which is a sort of electric resistance welding.

In a portable spot welding machine, the heat is created on the resistive raw materials through the contacting electrodes changes that travel on the metal surfaces.
