Pulse heating principle: Due to the special design of the welding head surface, the resistance of the welding surface is very small, and the current will pass through the section with the smallest resistance. By continuously changing the voltage and adjusting the current level, the welding head is made to heat up rapidly.

Refrigerated air dryer, also known as a refrigerated compressor. The amount of water vapor in compressed air is determined by the temperature of the compressed air: while keeping the compressed air pressure basically unchanged, reducing the temperature of the compressed air can reduce the water vapor content in the compressed air, and the excess water vapor will condense into liquid. Refrigerated air dryers (refrigerated dryers) use this principle to dry compressed air using refrigeration technology.
