SAFETY WARNING On the process of welding or cutting, there will be possibility of injury, so please take protection into consideration during operation. For more details please review the Operator Safety Guide, which complies with the preventive requirements of the manufacturer. Electric shock——May lead to death !...
MACHINE DESCRIPTION Welding machine is a rectifier adopting the most advanced inverter technology. The development of welding equipment benefits from the appearance of the inverter power supply theory and components. Inverter arc welding power source utilizes high-power component MOSFET to transfer 50/60Hz frequency up to 100 KHz, then reduce the voltage and commutate, and output high-power voltage via PWM technology.
INSTALLATION INSTRUCTION The machine is equipped with power voltage compensation equipment. When power voltage fluctuates between±15% of rated voltage, it still can work normally. When use long cable, in order to prevent voltage form going down, bigger section cable is suggested. If cable is too long, it may affect the performance of the power system.
OPERATION INSTRUCTION TIG Welding Description 1. Turn on the power switch of front panel, digital current meter is normal, fan begins to run. 2. Turn on argon switch, and adjust gas pressure to rated value.(refer to flow table). 3. Press switch of torch, electromagnetic valve is started. You will hear the sound of electricity-releasing HF sparkle and at the same time, argon gets out the torch.
NOTES OR PREVENTIVE MEASURES 1. Environment 1) The machine can perform in environment where conditions are dry with a dampness level of max 90%. 2) Ambient temperature is between -10 to 40 degrees centigrade. 3) Avoid welding in sunshine or drippings. Do not let water enter the gas 4)...
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.
MAINTENANCE WARNING: Power must be turned off for all checking and maintenance, before opening the housing, make sure the power plug is disconnected. Remove dust by dry and clean compressed air regularly, if welding machine is operated in environment where is polluted with smokes and polluted air, the machine need remove dust every month.
NOTICE: In the period of guarantee maintenance, if user makes wrong check and repair for malfunction of welding/cutting machines without our permission, the free maintenance guarantee offered will be invalid TROUBLESHOOTING AND FAULT FINDING Notes: The following operations must be performed by qualified electricians with valid certifications. Before maintenance,please contact with us for professional suggestion.

1. Maybe it is overheated protection, please close machine first, then turn on the machine again after abnormal indicator is out. 2. Maybe it is overheated protection, wait for 2-3 minutes (argon-arc welding does not has overheated protection function.) 3. Maybe inverter circuit is in fault, please pull up the supply power plug of main transformer which is on MOS board (VH-07 insert which is near the fan) then open the machine again.
