When bevelling and slag attach to the edges in CAC-A, it is a sign that the air pressure is too low. This could be because there is not enough air being fed into the welding area, resulting in a low pressure that is not strong enough to push and remove the excess slag and bevelling. The other options may seem like viable choices, but they would not result in bevelling and slag sticking to the edges. If the temperature was too high, the metal may melt too quickly and leave a rough, uneven edge. If the air pressure was too high, it could cause excessive sparks and splatter, but it would not result in bevelling and slag attaching to the edges. Lastly, if the electrode is too long, it may not create a proper arc and may not produce enough heat, but it would not cause bevelling and slag to stick to the edges. Therefore,
