Arc welding is widely used in various industries due to its simplicity and versatility. For a new welder, the most frustrating step in arc welding is learning how to strike an arc weld. The good news is that once you learn, it becomes second nature.

Difficulty: Challenging
Instructions
  1. Step 1

    Practice striking beads of weld on a piece of steel plate. Do this on two plates, both sides each. Arc welding is a process that involves practice. You may need to burn up to 40 lbs. of electrode to become proficient in striking an arc.

  2. Step 2

    Position the electrode approximately ½ inch away from the piece you want to weld and flip down your helmet. Jab the electrode quickly into the work and immediately pull it back. This is the jab method.

  3. Step 3

    Strike the electrode against your work, known as the striker, to make a weld. This is the strike method. Make sure that the stroke is quick so the rod doesn't freeze to the work.

  4. Step 4

    Turn up the amps if the rod freezes to the metal you're working on. Increase the amps by 10 at a time until the freezing stops.

  5. Step 5

    Pull the welding rod back about ¼ inch only. This will prevent it from going out once you strike the arc.

  6. Step 6

    Listen for a crackling noise to indicate that you're keeping the electrode at the correct distance. A popping noise with sparks means that it's too far away. If you keep it too close, it'll start to go out and you'll hear less noise.

  7. Step 7

    Stick the electrode back into the puddle if the arc goes out after you've started welding.
