J422 welding rod, 10MM steel plate.
Having a groove on a weld! If the current is higher, it will not pinch! It seems to be 140 degrees!
How is caught in the electrode holder do not have much relationship. The key is the angle between the electrode and the workpiece, horizontal fillet welding is quite appropriate at about 45 degrees.
A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.
