In MMA (Manual Metal Arc) Stick welding, Open Circuit Voltage (OCV) refers to the voltage that exists between the electrode and the workpiece when the welding machine is on, but no arc is struck. This voltage is crucial in determining how easily the arc starts and how stable it remains during the welding process. It…
Stick welding, also known as MMA (Manual Metal Arc) welding, can be made significantly easier through three modern features: Hot Start, Arc Force, and Anti-Stick. These features help improve welding performance, especially for beginners, and minimize common issues like electrode sticking and inconsistent arcs. Hot Start: Making Electrode Strikes Easier Hot Start is designed to…
To weld cast iron successfully, choose nickel-based electrodes (like 99% nickel) for the best crack resistance and machinability. If cost is a concern, 55% nickel rods provide a good compromise. Always preheat the metal to reduce cracking risk, maintain low amperage, and cool the weld slowly for best results. The Challenge of Welding Cast Iron…
