AG Mechanics CDE Practice Exam

Most MIG welding equipment is

1. automatic

2. manual

3. robotic

4. semiautomatic

The correct answer is: automatic

Most MIG (Metal Inert Gas) welding equipment is automatic because it operates with a continuous wire feed controlled by a trigger. This type of welding setup allows for a more consistent and efficient welding process as the wire feed and shielding gas flow are automatically adjusted based on the settings chosen by the operator. The automatic nature of MIG welding equipment reduces the potential for human error and results in cleaner, more precise welds. Options B, C, and D are not the best choices because manual welding equipment requires the operator to feed the wire by hand, robotic welding equipment is typically used for high-volume production with a fixed program, and semiautomatic welding equipment still requires some manual adjustment by the operator.
