ARC Welding

The arc welding power source produces heat to melt joints, generates a stable arc, and facilitates metal transfer. These functions are vital for effective welding. For example, using a transformer or inverter helps keep the arc stable during the welding process, ensuring strong and reliable welds. The characteristics of arc welding power sources vary widely. … Read more

Arc welding power sources include five main types: AC transformer, DC rectifier, AC/DC transformer rectifier, DC generator, and inverter. The control type, such as primary tapped, saturable reactor, thyristor, and inverter control, is important for choosing the right power source for different welding applications. When selecting an arc welding power source, consider its output characteristics. … Read more

Arc welding rod sizes depend on the application. For Flux-Cored Arc Welding (FCAW), electrode sizes generally range from 0.030” to 0.045”. The best rod size is determined by required weld penetration and the type of material being welded, ensuring effective and high-quality welds. For medium to thick metals, larger rods, such as those from 3/16 … Read more

Arc welding rods come in various sizes to match different metal thicknesses and applications. Common sizes are 1/16”, 5/64”, 3/32”, 1/8”, and 5/32”. The amperage ranges for these rods are 20-45 for 1/16”, 40-125 for 3/32”, 75-190 for 1/8”, and 105-250 for 5/32”. Select rod size based on plate thickness and your project needs. The … Read more

To prevent your arc welding rod from sticking, use the electrode striking technique. Start the arc while moving the rod to avoid sticking. Adjust your amperage settings; too low can cause issues. Ensure proper polarity for your electrode type. Finally, check your welding machine compatibility and settings for optimal performance. Improving your technique is equally … Read more

Arc welding rods mainly use tungsten and copper. Tungsten is durable and provides consistent heat for precise welding, but it is costly.
