Name: Full digital control inverter DC pulse TIG welding machine Model: DT315P Input voltage: three phase 380V Output Current: 315A current range :4-315A Weight: 30Kg functions: DC TIG, DC pulse TIG, DC MMA welding characteristics: OTC set of practical techniques in a change of a DC pulse TIG welding machine, digital inverter, IGBT speed control (80kHz). Two, containing 30 welding condition memory playback functions. Third, performance arc welding, arc stability, simple operation, forming and welding easy. Fourth, the ability to accurately control the back seam forming, heat input is reduced. Fifth, substantial miniaturization, weight (weight, volume of the original 1/2). Six, maneuverability, visibility is greatly improved. A set of standard components, welding power DT315P * 1 2, torch AWD-18 * 1 3, Ar gas meter AF-2502 * 1 4, trachea BKGFF-3803 * 1 5, welding cable BKPDT-3803 * 1 OTC TIG corresponding product has the following models: ①, OTC welding machine: DT315P ②, OTC welding machine: VRTPM-202 ③, OTC welding machine: AEP300.500 ④, OTC welding machine: AVP360. 500 ⑥, OTC welding machine: VRTP400 ⑦, OTC welding machine: DA300P ⑧, OTC welding machine: VRTP400 ⑨, OTC welding machine: DA300P ⑩, OTC welding machine: MR315T using OTC unique soft-switching-speed IGBT inverter control technology to improve the welding performance and lightweight miniaturization and high stability be achieved using an IGBT ◎ semiconductor components, using the newly developed soft-OTC switch control technology, IGBT control the speed of a staggering 80KHz, so in seeking to substantially smaller and lighter while welding performance is also greatly improved. Arc starting performance greatly improved, high frequency arc starting and double arcing contacts arcing way ◎ speed greatly improved due to the control, it is possible to precisely control the arc current waveform. Even a very small current of 4A and a cable extension, can be stably achieve instant arcing. Noise is small and very stable arc for the user to create a comfortable working environment thanks to the soft switch ◎ speed inverter control technology to achieve a close to full DC current waveform, making all-electric basin average lower noise levels 5dB. Plain and rich by setting the pulse function, to achieve high quality welding workpieces of various materials ◎ low pulse (0.1 ~ 20Hz) using low pulse and control heat input can be beautiful and uniform side welding seam, double-sided forming welds. Especially suitable for special welding, welding different thickness, there is a gap welding workpieces. ◎ High-speed pulse (20 ~ 500Hz) in the low valley high arc stability and arc focus and point of excellent, greatly improving the workability of welding plate. ◎ with DC manual welding with the use of more efficient the first layer on the base metal weld pulse TIG welding backing from the second floor to start using DC manual welding (2.5 ~ 5mm), can achieve high efficiency welding operations. User-oriented functional design ◎ reliability with the new machine casing structure, to achieve OTC welding machine high maintenance and high reliability. ◎ scalability to achieve broader applications, can easily connect with PC, plane and robot connection. ◎ technical OTC unique cross-intended remote control box and remote control box compatible digital technology.
