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.
WARNING! Creepage-protecting switch should be added when using the machine! ! ! MACHINE DESCRIPTION The 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.
WARNING! The machine is mainly used in industry. It will produce radio wave, so the worker should make fully preparation for protection. TECHNICAL PARAMETERS TABLE MIG 200 Model 1 phase Power Vol.(V) AC230V±15% Frequency(Hz) 50/60 Rated input current 37.4 (A)...
2) Insert the swift plug of earth cable into the swift socket in the front panel. 3) Set the wire wheel with wire on the wheel axis, the MIG 200 Installation: wheel hole should be matched with the wheel fixer.

OPERATION INSTRUCTION Put the air switch to “ON” position, open the valve of argon cylinder and adjust the flow. Adjust the wire diameter of the wire machine to rated number according to wire diameter. Choose torch loophole span based on wire diameter. 4.
NOTES OR PREVENTIVE MEASURES 1. Environment 1) The machine should be operated in dry environments with humidity levels of max 90%. 2) Ambient temperature should be between -10 to 40 degrees centigrade. 3) Avoid welding in sunshine or drippings. Do not let water infiter the machine. 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. Arcing-striking is difficult and easy to pause: 1) Make sure the earth cable clincher connects the work piece well. 2) Check each connecting point connected or not.
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. Fault symptom Remedy 1. Make sure air switch is closed. 2. Check if electric wire net is in work. 3.
EARLIER CHECKING DIAGRAM FOR THE ABNORMAL When abnormal situation such as failure of welding, unstable arc, poor welding result, do not consider that it must be some faults. The machine may be well but just some reasons cause abnormality such as that some connectors are loosened, forget to turn on the switch, wrong setting, broken cable and gas pipe, etc.

EARLIER CHECKING DIAGRAM FOR THE ABNORMAL WARNING: If not necessary, before checking the power supply box must be cut off to insure security. Violating the above principle, it will lead to serious accident threatening life safety like electric shock and burning EARLIER CHECKING DIAGRAM FOR THE ABNORMAL The abnormal Place and item to be checked...
DAILY CHECKING WELDING POWER SUPPLY Position Checking keys Remarks 1. Switch condition of operation, transfer Control and installation. panel 2. Test the power indicator. Cooling 1. Check if there is wind and the sound If abnormal noise and no wind, to normal or not.
