Question 18 (1 point) When welding with a MiG welder, the ground clamp is not neccessary since it is an automatic wire feed. True b False

## Step 1<br />The problem is about the use of a ground clamp in MIG (Metal Inert Gas) welding. The ground clamp is a crucial component in welding, as it provides a return path for the current. This is necessary to complete the circuit and ensure the proper functioning of the welding process.<br />## Step 2<br />The statement in the problem suggests that the ground clamp is not necessary in MIG welding because it is an automatic wire feed. However, this is not correct. The automatic wire feed does not eliminate the need for a ground clamp.<br />## Step 3<br />The ground clamp is necessary in MIG welding to ensure the safety of the welder and the quality of the weld. It provides a return path for the current, which is essential for the proper functioning of the welding process.
