2. MACHINE DESCRIPTION The welding machine is a rectifier adopting the most advanced inverter technology. The development of inverter gas-shielded welding equipment benefits from the development of the nverter power supply theory and components. Inverter gas-shielded welding power source utilizes high-power component IGBT to transfer 50/60Hz frequency up to 30~50KHz , then reduce the voltage and commutate, and output high-power voltage via PWM technology. - Page 5 ccording to input voltage grade, connect power cable with power supply box of relevant voltage de. Make sure no mistake is made and make sure the voltage difference is among permission ge. After the above job, installation is finished and welding is available. OPERATION INSTRUCTION onnect AC220V power supply.

of voltage will assure that welding current keeps in allowable range. If power voltage is exceeding allowable range limited, it will damage to components of machine. The operator should understand this situation and take preventive measures. 4) If welding time is exceeded duty cycle limited, welding machine will stop working for protection. Because machine is overheated, temperature control switch is on “ON’’... -

D. Too much spatter when use MMA welding, 1. Maybe current is too big and stick’s diameter is too small. 2. Output terminal polarity connection is wrong, it should apply the opposite polarity at the normal technics, which means that the stick should be connected with the negative polarity of power source, and work piece should be connected with the positive polarity.
