Electric welding machine welding, welding rod old stick metal, welding rod burning red, very scary

Answer:

The arcing contact electrode and the work piece the wrong way, do not use too much force at the contact electrode, which is slightly floating, in addition to improve the current, can be adjusted according to the electrode packing instructions, you practice more, don't worry, I believe you will succeed.
Several heroes are very practical, welding electrode drying before use is also necessary!
1, this is because you are novice unskilled operation caused,2, teach you two kinds of arc welding method:1) scratch: this method is easier to control, but it is easy to damage the surface of weldment. The welding rod shall be aligned with the weldment at first, then the electrode will be lightly scratched on the surface of the weldment as a match. The arc will be ignited, and then the electrode will be improved by about 2-4mm, and it will be stably ignited.2) direct method: the end of the electrode aligned welding parts, and then bend the wrist, so that the electrode slightly touched the weldment, and then quickly put the electrode about 2-4mm, arc ignition, wrist flat, so that the arc to maintain stable combustion. The method does not scratch the surface of the weldment and is not limited by the size and shape of the weldment surface, so it is widely used in production. But this method is not easy to master, the welder must have higher proficiency in operation.3) starting welding: after the arc is ignited, the arc will be lengthened a little longer, the butt welding parts should be preheated as necessary and appropriate, then the arc should be pressed properly and transferred to the normal welding procedure.3, usually practice more, do not worry, I believe you will succeed.
