Welding points for electrode arm welding

Welding points for electrode arm welding:

Ignite an arc on the right side of the positioning weld seam, preheat in place, and temporarily do not add wire. After the positioning weld seam and the grooves on both sides melt to form a molten pool, the arc moves to the left side of the positioning weld seam, lowers the arc, hears a breakdown sound, sees a molten hole, and when the diameter of the molten hole is appropriate, turn to the positive left welding mode and start adding wire.
