Troubleshooting
| PROBLEMS | CORRECTION |
| Lack of penetration | Increase current / use electrode +ve / decrease voltage / decrease stickout / decrease travel speed / decrease electrode diameter. |
| Cracking | Lower voltage /decrease welding speed / Increase electrode diameter / pre-heat joint / avoid concave reinforcement. Increase interpass temperature. |
| Pock marks | Increase voltage / decrease curren ./ the joint / decrease speed / use Si containing electrode / use in Si active flux. |
| Slag sticking | Decrease voltage and current. |
| Porosity | Increase voltage / decrease current / the joint / decrease speed / flux coverinadequate-use finer flux fraction / gougeout contaminated weld backing. |
| Cracks | Pre-heat required / improper cooling check interpass temperature / use Si active flux / lower voltage / decrease welding speed / increase included angle. |
| Burn through | Decrease current / increase travel speed / increase wire size |
| Surface discolouration / spots | Decrease current and voltage / increase weld speed / dry the flux |
