| WELDING PROBLEMS |
|
|
|
|
|
|
|
|
| |
Excessive spatter | 1. | Improper welding polarity. | 1. | Make sure the electrode holder is |
| |
|
|
|
|
| plugged into the positive “+” out- |
|
|
|
|
|
| put terminal. |
|
|
| 2. | Long Arc Length. | 2. | Move the electrode closer into the |
|
|
|
|
|
| weld joint. |
|
|
| 3. | High Current. | 3. | Turn the output knob down. |
|
|
|
|
|
|
| |
Craters | 1. | Fast movement of the electrode | 1. | Maintain a steady consistent arc |
| |
|
|
| away from the work piece. |

Inclusions | 1. | Poor cleanliness. | 1. | Clean work piece with wire brush |
| |
|
|
|
|
| prior to welding. |
|
|
| 2. | Poor distribution of the welding | 2. | Consult a welding guide for proper |

| passes. |
| weld bead placement. |
|
|
|
|
|
|
| |
Insufficient penetration | 1. | High travel speed. | 1. | Travel at a slower speed. |
| |
|
| 2. | Welding current is too low. | 2. Adjust welding output higher. |
| |
|
|
|
|
| ||
Electrode Sticking | 1. Arc length is too short. | 1. | Move the electrode further away |
| ||
|
|
|
|
| from the weld joint. |
|
|
| 2. | Welding current is too low. | 2. | Turn the output knob up. |
|
|
|
|
|
|
| |
Porosity | 1. | Humidity in the electrode. | 1. | Store welding electrodes in a |
| |
|
|
|
|
| warm dry place. |
|
|
| 2. | Long arc length. | 2. | Move the electrode closer into the |
|
|
|
|
|
| weld joint. |
|
|
|
|
|
|
| |
Cracks | 1. | Weld current is set too high. | 1. | Turn the output knob down. |
| |
|
| 2. | Dirty materials. | 2. | Clean work piece with wire brush |
|
|
|
|
|
| prior to welding. |
|
|
| 3. | Hydrogen in the weld due to mois- | 3. | Store welding electrodes in a |
