DC Spot Welding Machine
Description
DZ, TZ series DC spot welding machine or DC spot welder makes use of welding transformer. This transformer adopts high-power silicon diode to perform rectification, changing AC to DC welding of work pieces. And compressed air is adopted as driving and welding pressure. The whole welding process is accomplished by KD or KD3 series controller.
Features of DC Spot Welding Machine
1. The upper electrode makes perpendicular movement, so DC spot welder has stable regulation function.
2. It features stable welding pressure, high control accuracy and power factor, low energy consumption and stable quality.
3. The operation is controlled by stepped switch, which is of high producing efficiency and low labor strength.
Application of DC Spot Welding Machine
Besides low carbon steel, coated steel, stainless steel, heat-resisting alloy, copper, aluminum and alloy, DZ, TZ series DC spot welder is capable of welding rare metals like titanium, niobium, barium and zirconium and multilayer steel plates. In addition, it is widely applied in various industries, such as automobile, voyage, aerospace, atomic energy and wireless industrial sector, etc.
Classification
DC spot welding machine can be classified into the following types.
1. Single-Phase Secondary Rectifier DC Spot Welder
2. Three-Phase Secondary Rectifier DC Spot Welding Machine.
