IF spot welding machine is the focus of the promotion of energy-saving welding equipment, is also designated by the state to replace the rotating DC ideal for welding equipment. IF spot welder is now widely used in automotive. shipbuilding, metallurgy, chemical, construction and other industries, can be widely made welding electrode, the low carbon steel, medium carbon steel, low alloy steel and stainless steel, it can Medium frequency spot welding machine using the rapid control of the characteristics of SCR components, IF spot welding characteristics of excellent, soft performance, stable arc, the pool calm, splashing, splashing, welding, Small, good weld shape, is conducive to overcome the alkaline electrode in welding the tendency to produce pores.
