The Insulator is an integral part of the Asian welding torch. His materials are mainly made of polymer materials and brass die-cast for insulation. Commonly used on Panasonic torches and OTC guns. The colors we see are black and yellow.

The outer circumference of the rotor of the motor conical rotor is tapered, so the rotor punching process cannot use the double-die punching process used in ordinary motors, and the single-slot punching method is generally adopted. After the rotor is pressed, there is a jagged phenomenon. If the inner hole is not processed, it is difficult to meet the pattern requirements. Therefore, after the tapered rotor is cast aluminum, we use a self-propelled pusher to iron the shaft hole.
