Page 5: General Introduction
GEN ER A L IN TR ODU C T I ON RIRCHMOND CT312, CT416 and CT520 are multi-functional welders made with state-of-art inverter technology. They have three functions: TIG, MMA, and CUT. The advanced inverter technology used in our welders and cutters allows for converting 50/60Hz working frequency to high frequency of up to 100Hz, with high power factor V-MOS, and then reducing and rectifying the voltage, and producing a high power output with PWM for welding and cutting, thus greatly reducing the weight and size of the main components (transistors), and, at the same time, raising the efficiency by 30％. -

Page 12: Working Environment
IV. CAUTIONS 4-1 Working Environment (1) The location where this machine is placed should be of little dust and no corrosive chemical gases or flammable gases and materials, with maximum moisture of no more than 80%； (2) Do not operate this machine in the open air unless the working area is sheltered from the sunshine, rain, water, snow, etc. -
Page 13: Maintenance
V. MAINTENANCE Clear the dust at regular intervals with clean and dry compressed air. Set the air flow at a reasonable pressure to avoid damaging small parts in the machine. If the working area is dusty, damp and heavy in smoke or corrosive gases, this machine should be cleaned at least once a month. -
