Page 2: Safety Precautions
Safety precautions ● Please read this instruction carefully for correct use. ● The objective of the precautions listed in this instruction is to ensure the safe use of machine and prevent you and others from being harmed or injured. ● Safety consideration for the welding machine in design and manufacture. - Page 3 Accident 1. Safety consideration for the welding machine in design and manufacture. Work to the precautions in this instruction, otherwise it will cause death, serious injury and other major personal accident. 2. For the construction power source of input, the choice of equipment location, the application keeping and configure of high pressure gas, the keeping of workpiece after welding and the treatment of rejection and so on, please observe the relative regulations and the standards inside your company.
- Page 4 9. Make maintenance and examination and repair, only the damaged part can by use until it is repaired well. 10. Please shut off all input powers when the machine is unused. 11. When use AC arc welding machine in the confined place or high place, please use electric shock-proof device.
- Page 5 1. Never place combustible in the weld location. 2. Never weld near combustible gas. 3. Never close to the combustible when the heat parent metal is just welded. 4. When weld dooryard, ground and wall, please eliminate the combustible on the back. 5.
- Page 6 1. In affirming whether the welding wire is fed, do not peek into the small hole of current contact nozzle. Otherwise welding wire will prick eye and face. 2. When welding wire is fed by hand or welding torch is opened, please do not put the end of welding torch dose to eye, face and other exposure parts of the body.

Page 7: Working Directions
Working Directions ■ Load Duration Factor Load duration factor refers to the ratio that practical work time accounts for the whole work time (10 minutes is 1 cycle). For example, 60% load duration factor means that weld is made for 6 minutes and then zero load is for 4 minutes. - Page 8 2. Especially for fuse and other current protectors, for the sake of safety, please use the protector with proper capacity rather than the protector with the too great capacity. 3. Connection of welding end One end connects with the cable of welding tongs, another end connects with welded object by connection cable.

(6) Positive electrode output: the socket connecting soldering tongs at manual welding. (7) ARC FORCE: it can change the time of arc stopping of argon arc welding to adjust the button.
- Page 12 (2) Check whether the automatic air switch is put upward onto the position of connection or not. (3) Check whether option switches regulating operating mode and control mode on the front panel are in the right position. 2. Examination under power-supply and no load (1) If power-on is successful, the indicating lamps of power lights up.
- Page 13 Schematic diagram for intermediate plates (Picture 7) . Installation and debugging 1. Environment (1) The welding operation shall be operated in a relatively dry environment, and the air humidity should not exceed 90 percent. (2)The ambient temperature should be between -10%℃ and 40℃. (3)Do not weld under the sunlight or in the rain, and do not let water or rain go into welding machine.
- Page 14 (3) To prohibit over voltage! The power voltage is listed in the main technique parameters such as these in form 1, in normal conditions; the voltage auto-compensation circuit in the welder limits the welding current within normal range. If the power voltage exceeds the normal range, the welding machine will be damaged.
