1) Do not use a welding current higher than the recommended range. (As attached to the wire box), because not only will it reduce the ability of X-ray inspection. It also causes a lot of welding flakes, causing edge bites. And the cover of the slack is not good enough.
2) to get the best results The electrodes should be heated before use at 70-100 C for 30-60 minutes. Excessive moisture absorption of the electrodes will lower the working properties of the electrodes. And may cause air bubbles to build up in the weld
