Welder welding is to provide a certain characteristic electrical power, welding due to the flexible and easy to be solid and reliable, even with the advantage after welding base material of equivalent strength for lack of a wide range of industries, such as aerospace, shipbuilding, automobiles, containers.
Welder (electric welding machine) actually has decreased the external characteristics of the transformer, the 220V and 380V AC into low voltage direct current, welding generally based on the output power can be divided into two types, one is the AC power; one kind is direct current. DC welder can say this is a high-power rectifier, positive and negative points, AC input, after transformer transformer, then rectified by the rectifier, and the drop in output characteristics with the power output of the ON and OFF will produce a great change in voltage at the moment of arc ignition bipolar short circuit generated by the arc to melt the electrode and welding, so that they reach the cooling was bound object. Welding transformer has its own characteristics, external feature is a sharp decline after the ignition electrode voltage characteristics

In the coming five years, kitchen and bathroom products are expected to see steady growth. As living standards improve and housing conditions become better, manufacturers are continuously enhancing the functionality and comfort of their offerings. In recent years, these products have become more household-oriented, aligning closely with the needs of modern families. Consumers are increasingly drawn to stylish and innovative designs, such as near-suction range hoods, European-style range hoods, built-in sterilizers, and integrated gas stoves, which have seen strong market performance.
At the 2013 China Kitchen Industry Development Forum in Shanghai, Peng Yi, Deputy General Manager of Zhong Yikang, stated that the kitchen and bathroom industry will maintain a compound annual growth rate (CAGR) of around 10% over the next five years. This projection is based on historical trends and current market dynamics. For instance, after a 4.8% decline in 2012 due to factors like reduced financial incentives and real estate regulations, the market rebounded sharply, growing by 17.6% in the first three quarters of 2013. The total market size surpassed 1 trillion yuan, with an estimated full-year value of about 1.3 trillion yuan.
The strong recovery can be attributed to several factors, including the rebound in the second-hand housing market, energy-saving subsidies, and continued urbanization. With more people moving into cities, consumer lifestyles are changing, creating greater demand for kitchen and bathroom products. Compared to other home appliances, the ownership rate of kitchen and bathroom products in China is still relatively low, providing significant room for future growth.
Online sales are also playing a key role in expanding the market. While the urbanization rate in China has exceeded 50%, only about 35% of the population resides in urban areas, far below developed countries. This shift in demographics is driving demand. Additionally, e-commerce is becoming a major channel for kitchen and bath products. According to Yikang's data, online sales of these products grew by 17.6% year-on-year in the first three quarters of the year, with e-commerce channels seeing a staggering 185.7% growth—20 times faster than offline sales.
Looking ahead, the kitchen and bathroom industry is poised for substantial growth. Peng Yi believes that the CAGR for this sector will be 10% over the next five years, outpacing the overall home appliance market by 4 to 5 percentage points. By 2016, the industry is expected to reach 199.5 billion yuan. Future products will be more intelligent, energy-efficient, and system-based. Online platforms will play an even bigger role, with kitchen and bathroom product sales through e-commerce projected to exceed 16.8 billion yuan in 2014. By 2016, online home appliance sales could reach 400 billion yuan, accounting for 27.5% of total home appliance sales.
