Page 3: Safety Warning
SAFETY WARNING On the process of welding or cutting, there will be any possibility of injury, so please take protection into consideration during operation. More details please review the Operator Safety Guide, which complies with the preventive requirements of the manufacturer ——may lead to death ! ! Electric shock ·Set the earth fitting according to applying standard. -
Page 4: Machine Description
MACHINE DESCRIPTION Welding machine is a rectifier adopting the most advanced inverter technology. The development of inverter gas-shielded welding equipment profits from the development of the inverter power supply theory and components. Inverter gas-shielded welding power source utilizes high-power component MOSFET to transfer 50/60HZ frequency up to 100KHZ, then reduce the voltage and commutate, and output high-power voltage via PWM technology. -

Page 6: Installation Instruction
INSTALLATION INSTRUCTION The machine is equipped with power voltage compensation equipment. When power voltage moves between±15% of rated voltage, it still can work normally. When use long cable, in order to prevent voltage from going down, bigger section cable is suggested. - Page 7 When use MMA function Power supply (1phase ~ 110/220V) Connected to the ground When use TIG function Power supply (1phase ~ 110/220V) Connected to the ground warning！ Before connecting operation please make sure all the power is turned off. The right order is to connect the welding cable and ground cable to the machine first, and make sure they are firmly connected and then put the power plug to the power source.

Page 10: Notes Or Preventive Measures
NOTES OR PREVENTIVE MEASURES 1、Environment 5）The machine can perform in environment where conditions are dry with a dampness level of max 90%. 6）Ambient temperature is between -10 to 40 degrees centigrade. 7）Avoid welding in sunshine or drippings. 8）Do not use the machine in environment where condition is polluted with conductive dust on the air or corrosiveness gas on the air. -
Page 11: Questions To Be Run Into During Welding
QUESTIONS TO BE RUN INTO DURING WELDING Fittings, welding materials, environment factor, supply powers maybe have something to do with welding. User must try to improve welding environment. A、Black welding spot ——Welding spot is not prevented from oxidizing .User may check as following : 1. -
Page 12: Maintenance
MAINTENANCE CAUTION： Before Maintenance and checking, power must be turned off, and before Opening the housing, make sure the power plug is pulled off.. 1、Remove dust by dry and clean compressed air regularly, if welding machine is operating in environment where is polluted with smokes and pollution air, the machine need remove dust every month 2、... -
Page 13: Before Checking
BEFORE CHECKING WARNING Blind experiment and careless repair may lead to more problem of the machine that will make formal check and repair more difficult. When the machine is electrified, the naked parts contain life-threatening voltage. Any direct and indirect touch will cause electric shock, and severe electric shock will lead to death.
