Product description: Whole features: Vacuum electron tubes, the output power is stable and reliable. Sensitive sparks overcurrent protection circuit. Can automatically cut high-frequency/vacuum suppress sparks. Stabilizer in the same manner and frequency with high-frequency/vacuum shielding devices and high-frequency interference minimum. Die set manually adjust to facilitate test mode. Automatically fusion process, and improve working efficiency. Temperature levels without heating system, melt more quickly. Over-current protection system automatically spark growth for vacuum life. Mold damage protection. 4kw40.68MHz.5.12kw27.12MHz International Standard Industrial band. Germany's "CKC" time, the precise time lock installed. German high pressure silicone tube. Germany "semikron" pneumatic components. Japan's "OMRON" relays, micro-switches. Italy enormity of temperature regulation system.
