(1) the use of vacuum tube, the output power, stable and reliable performance 
 (2) high sensitivity spark over-current protection circuit. Can effectively cut off due to high current output is too large mold damage, more effective control of spark 
 3 with the high-frequency frequency stabilizer and high frequency shielding to minimize high frequency interference 
 Equipped with overcurrent protection system, to increase the useful lives of the vacuum tube 
 Pneumatic power pressurized way to reduce the intensity of the work, to enhance the quality of voltage products 
 6. Installation of high-precision temperature control to ensure welding consistency 
 Four horizontal adjustment, the transfer mode is easier and quicker Province 
 Positioning device, accurate positioning
