ASE-Style Multiple Choice While having a discussion, Technician A says that if the tip-to-base metal distance is too long, the length of wire protruding from the end of the gun increases and becomes preheated, which increases the melting speed of the wire. Technician B says that if the tip-to-base metal distance is too long, the shield gas effect will be reduced. Who is correct?

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. If the tip-to-base metal distance is too long, the length of wire protruding from the end of the gun increases and becomes preheated, which increases the melting speed of the wire. Additionally, the shield gas effect will be reduced, as the gas will have to travel a longer distance to reach the weld pool.
