In recent years, foreign manufacturers to develop a new technology called precision plasma or called high-precision plasma, the domestic manufacturers have been introduced. Better. By improving the design of cutting torch, compared with significantly improved the quality of the cut surface of the workpiece, Shao edge of up to 0-1.5 ° vertical planks to improve cutting quality is particularly advantageous. Due to improved torch cutting, electrode life has been several times to improve. But the torch from higher steel distance demands to cut the height sensor is more sensitive reaction on the gun straight cutting machine, cutting torch lift more responsive. Therefore, the use of plasma cutting 4-30 mm steel plate is the ideal way to underwater cutting, cutting to avoid lack of oxygen B slow, large deformation, cut Rong serious, dross serious shortcomings. Obtained under a certain thickness of the stainless steel material and other materials. Cutting Process: Pre-ventilation - the main circuit power supply - frequency arc - cutting - interest arc - stop. Powered by the main circuit contactor control; through short gas controlled by a solenoid valve; a high-frequency oscillator by the control circuit controls the ignition arc, and after the establishment of the high-frequency arc stop working. Furthermore, the control circuit still has the following internal lock function: thermal switch is activated to stop working. Underwater cutting, Wuhan three Rainbow Heavy Industries (online consultation), cut by three Rainbow Heavy Industries Ltd. of Wuhan. Wuhan three Rainbow Heavy Industries Ltd. (www.whshzg.com) is Wuhan, a leader in welding equipment and equipment over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three Hong Heavy Industries in Wuhan leadership with the staff warmly welcome all inquiries negotiations to create Wuhan three Rainbow Heavy Industries better future.
