(1) First, inject some diesel into the hole of the Tap pitch, and then place the workpiece in the horizontal direction of the Tap pitch to make it easy to remove the slag.  

(2) If the surface roughness of the workpiece is required to be high and it is not allowed to attract foxes on it, a small iron plate can be prepared for attracting foxes.  

(3) Use a buckle head protective face mask. This way, one can hold the welding tongs with one hand and firmly hold the workpiece with the other hand, so that the small workpiece will not be knocked over when the welding electrode ignites the arc. After the welding electrode is ignited, it should be quickly aligned with the center of the Tap machining to form a high-temperature arc column. When operating, the welding tongs should be held firmly to prevent the welding from contacting the workpiece, in order to avoid burning out the threaded holes.  

(4) After the Tapping tap starts to melt, the welding electrode should be slowly pushed forward. When the cutting sound is different from the beginning, it proves that it has been cut through. The welding electrode should be pulled out immediately, and after cooling, the slag should be gently knocked out with a pointed chisel.
