No. 9 Shield is excellent for low to medium amperage (50-140A) welding. Unlike traditional lenses where the arc and puddle are green, this gold lens creates an arc and puddle ranging from yellow to orange, which is more relaxed for the eyes and allows for longer sweat times. I have used this lens in several welding processes such as SMAW (electrode welding), GMAW, TIG and FCAW. I would not recommend using this lens when welding at high current (170 amps and up), get a darker lens.
