How is connection between electrode holder and welding machine?

The connection between the electrode holder and the welding machine is typically made through a cable that transmits electrical current. This cable is connected to the welding machine's output terminal, allowing the flow of electricity to the electrode holder. The electrode holder itself clamps the welding electrode securely, ensuring proper contact and heat generation during the welding process. Proper connections are essential for achieving efficient welding performance and minimizing energy loss.
