Welding and cutting equipment known as the 'industrial sewing machine, plays a vital role in the process of industrial development today, nearly half of the world's metal products had to use welding to complete the connection. However, the traditional exchange of welding and cutting equipment is high-energy-consuming products, the Ministry of Industry and Information Technology, Ministry of nearly two years of continuous announcement, the traditional exchange of welding and cutting equipment included in the 'high energy behind the mechanical and electrical equipment (products) out of the directory), accelerate the elimination of widely used in industrial boilers in the national economy, small and medium-sized motors, welding machines and other high energy behind the production and use of mechanical and electrical equipment products.

Inverter welding and cutting equipment due to the high operating frequency, fast response, good welding performance, energy saving, small size, light weight, is conducive to the realization of welding automation, etc., has become the development direction of welding and cutting equipment, is gradually replacing the traditional welding cutting equipment, showing a trend of rapid development.

Inverter welding and cutting equipment itself, the size and weight is greatly reduced, and weighs only traditional welding 1/5 to 1/10, to facilitate the production, transport and use, and can save a lot of metallic materials in the manufacture of welding and cutting equipment (mainly for the consumption of copper, silicon steel, aluminum, etc.). At the same time, the corresponding effective power output of the inverter welding and cutting equipment greatly improved, can reach 82% to 93%. Traditional welding and cutting equipment effective power output of only 40% to 60%, a serious waste of power resources.

China has become the welding and cutting equipment, welding and cutting equipment market capacity in 2009 reached 200 billion yuan, but a lower proportion of inverter welding and cutting equipment, around 28%, about 60% to 70% the level of developed countries in the world, domestic inverter welding and cutting equipment room for growth is huge. From the production and sales of inverter welding and cutting equipment, inverter welding and cutting equipment production annual growth rate of about 20%, the growth rate is much higher than the growth rate of the traditional welding and cutting equipment, instead of the traditional inverter welding and cutting equipment the trend of welding and cutting equipment.
