Mixtures of argon with less than ____ percent carbon dioxide may not have enough arc voltage to give desired results.

Question

Quizplus · Accepted Answer

Argon is often used as a shielding gas for welding because of its non-reactive nature. However, when mixed with other gases like carbon dioxide, its electrical properties can change, affecting the performance of the welding arc. To ensure proper arc voltage and desired results, it is recommended to use mixtures of argon with at least 10% carbon dioxide. Therefore, choice B (10) is the best answer.

Mixtures of Argon with Less Than ____ Percent Carbon Dioxide
