Safe, reliable and convenient for searching the malfunction. 4) Small volume, light weight, high efficiency and energy saving. The loading and persisting rate are excellent and there is no noise in the TIG rectifier. 5) With the reasonable contruction and the concise layout, servicing is advantageous. 6) Is suitable for any trademark of welding rod to carry on the direct current manual welding. 7) The welding machinc can still output enough welding current even the length of electric cable reaches 50Ms. 8) Equipped with the arouse arc and thrust adjustment,our machine is strongly applicable in any kind of welding craft. 9) Can be used as a simple DC TIG welding electric power supply,one machine with the multiple functions(Can be applied merely in the ST series). 10) With the IGBT high frequency inversion technology, our machine can guarantee the welding voltage stays in a highly steady situation under the undulation of voltage of electric network and the changes of the electric arc length. 11) Uses the special control mode, the output current is constant, strong ability to resist the undulation of voltage of electric network and the welding environment disturbance abilities are strong. 12) Stable electric arc ,few splashes, high metal melt spreading, elegant, welding seams and little welding deformation. 13) Direting arc by strong pulse, easy in arc initiating which enables high rate of successful operation. 14) Our machine contains the eliminating ball function when arc ending happens. 15) The self-locking function can reduce the welders laboring intensity when dealing with the large-scale and long welding seams work.
