An electrode ending with the number 8 contains iron powder and is also a low-hydrogen electrode. A True B False

## Step 1<br />The problem is about the classification of electrodes in welding. The electrode ending with the number 8 is known as a low-hydrogen electrode. This is because it has a low hydrogen content, which is crucial in welding to prevent hydrogen-induced cracking.<br />## Step 2<br />The problem also mentions that this electrode contains iron powder. Iron powder is a common ingredient in welding electrodes, as it provides the necessary metal for the welding process.<br />## Step 3<br />Given the information provided, the statement that an electrode ending with the number 8 contains iron powder and is also a low-hydrogen electrode is true.
