Recommended amps for arc welding depend on electrode size. For stick welding: 1/8 inch requires 75-125 A; 5/32 inch needs 110-170 A; 3/16 inch needs 140-215 A; 7/32 inch needs 170-250 A. Use the correct amperage for the best welding results. Additionally, consider the type of electrode. E7018 electrodes function well on thicker steel and … Read more

For arc welding, the American National Standards Institute (ANSI) recommends shade numbers based on arc current. Use shade 12 for Gas Metal Arc Welding (GMAW) at 160-250 amps. For GMAW at 250-500 amps, use shade 14. For Gas Tungsten Arc Welding (GTAW), shades range from 10 to 12, depending on the current. Using the correct … Read more

Red arc welding electrodes have different classifications, such as E7018, which is suitable for mild steel and low alloy steel. The “E” stands for electrode, and the numbers indicate strength and design. Low hydrogen electrodes (Exxx5) ensure better quality welds. Understanding these electrodes helps in choosing the right one for your welding process. For example, … Read more
