DCT series TIG pulses TIG digital IGBT inverter

DCT series TIG pulses TIG digital IGBT inverter,using microcomputer control, has high accuracy and stability,and had been designed a good human-computer interface, single-knob preset parameters, real-time adjustments, in line with traditional habits. TIG arc welding has good striking for using high-voltage pulse, even as the 50 meter lenght of torch cable Main Features: ² Using a microcomputer control, high accuracy(such as pulse time accuracy of 1 mS, current regulation accuracy of 0.1 A.) and stability have been provided. ² Using high-voltage pulse striking arc, there is a high success igniting rate, even though 50 meters length of torch cable. ² Single-knob adjustment parameters, Electronic Touch Control Panel, Good human-computer interface. LEDs figure on panel indicats a procedure status, the LED indicator shows each procedure preseting the parameters and displays real-time welding procedures process. ² PLC of pulse TIG welding has 10 sections: pulse peak/base current, width of the pulse peak/base, striking/cratering current, welding upslope/downslope time, pre- /post-flow time. ² Parameters of the any procedures can be preseting and adjusting real-time. ² Ten sets of welding parameters of both Pulse and DC TIG welding can be storage and call. ² With power-fail protection of welding parameters storage, power outage would not cause the accidental loss. ² Boot to the implementation of last used by the welding parameters. ² Through the software updates, welder can be upgraded. ² Small size, light weight and high rated duty cycle, high efficiency and energy saving.
