An electrode specifically designed for use with 100% CO2 will have higher levels of ____ to compensate for the losses to oxidization.
A) silicon and manganese
B) argon and carbon
C) titanium and vanadium
D) aluminum and potassium

Question

Quizplus · Accepted Answer

Silicon and manganese are commonly added to electrodes used with 100% CO2 to compensate for the losses to oxidization. These elements help to stabilize the arc and prevent excessive spatter. Argon and carbon are not typically added to electrodes for use with CO2, while titanium and vanadium may be added for other reasons (such as strength and corrosion resistance) but do not specifically compensate for oxidization losses. Aluminum and potassium are also not commonly used in electrodes for CO2 welding.
