What is the difference between THJ506 welding rod and THJ422 electrode?
The difference between the use of THJ506 electrodes and THJ422 electrodes is that:506 for the strength grade 50 kg grade steel welding. It can be used as AC and DC, but it is better to use DC welder422 for the strength grade 40 kg grade steel welding. AC and DC are available.
Fine, thanks for the answer
1, THJ506 electrode and THJ422 electrode in use is different.2, first of all, an acid welding rod, and an alkaline electrode.3, second electrode class is not the same, one is 40, one is 50.4, in the use of acid welding rod, DC welding machine can be welded.5, the basic welding rod welding machine is usually required to welding, because it requires welding machine no-load voltage is relatively high.6, THJ506 electrode in the description, it is possible to AC welding machine can be used, but in actual use, arc is very difficult, and even welding machine is not good, even the arc can not play, even if the arc, continuous welding is still very difficult.
