Page 3: I Product Introduction
I. Product introduction Product introduction WS-MX series inverter welder are proven product with stable performance which is manufactured with advanced invert welding technology. Its operating principle is that converts operating frequency of 50/60 Hz to direct current, then invert to high frequency at approximate 100 kHz, and performs voltage dropping and rectification by PWM and high power MOS field effect transistor (MOSFET), and then output high power DC power for welding by PWM. -
Page 4: Notice For Safety
II. Notice for Safety Notice for Safety IMPORTANT: ● Do not cut off power in order to prevent damage of machine during welding. ● Turn off control switch for cutting torch in order to ensure disconnection of cutting torch and base metal to prevent burning by electric arc before welding. -

- Page 13 V. Preparation and operating for welding 1. Confirm the quality of tungsten electrode is good. The discharge performance of tungsten electrode in bad quality may not meet relevant requirement. 2. The tungsten electrode without sharp treatment is not easy to arc and may cause arc to be unstable.
- Page 14 V. Preparation and operating for welding 3) Do not over voltage! Power voltage listed in “main performance parameters list”. Generally, automatic compensation circuit in welder may maintain welding current within allowable range required for normal operation. However, it may damage welder if power voltage exceeds power voltage. Operator must observe above condition and take proper preventive measures.
