Page 3: Safety Warning
SAFETY WARNING In the process of welding, there could be possibilities of injury, so please take protection into consideration during operation. For more details please read the Operator Safety Guide, which complies with the preventive requirements of the manufacturer. Electric shock——Can kill ！ Set the earth fitting according to applying standard. -
Page 4: Machine Description
MACHINE DESCRIPTION The welding machine is a rectifier adopting the most advanced inverter technology. The development of inverter MIG welding equipment profits from the development of the inverter power supply theory and components. Inverter MIG welding power source utilizes high-power component MOSFET to transfer 50/60Hz frequency up to 100 KHz, then reduce the voltage and change it to DC and then control the high-power output amperage via PWM technology. -

Page 6: Installation & Operation Instruction
INSTALLATION INSTRUCTIONS The welding equipment is equipped with power voltage compensation. When power voltage moves between ±15% of rated voltage, it will still work normally. When using a long cable, in order to minimize the loss of voltage a bigger section cable is suggested. If the cable is too long it will affect the performance of arcing and other system function, so stated length is recommended. -

Page 9: Notes Or Preventive Measures
NOTICES OR PREVENTIVE MEASURES 1、Environment 1） The machine can perform in environments where conditions are dry to a humidity level of max 60%. 2） Ambient temperature of -10 to 40 degrees centigrade. 3） Avoid welding in direct sunshine, in rain or wet areas. 4）... -
Page 10: Questions
QUESTIONS The following can cause problems with welding: Fittings, welding materials, environmental factors, power supply and welding technics. User must try to improve welding conditions. A、Difficulty Arcing-striking 1) Make sure the earth cable is clamped to the work piece. 2) Check each connection point of earth cable.(pull to make sure tight connection) 3) Welding torch tightened on machine. -
Page 11: Maintenance
MAINTENANCE WARNING! Before maintenance and checking, power must be turned off, Before opening the cover disconnect the machine from electricity! 1. Remove dust with dry, clean compressed air regularly, if the welding machine is operated in an area where the air is polluted with smoke and dust, the machine needs to be cleaned regularly, remove dust monthly. -
Page 12: Daily Checking
DAILY CHECKING WELDING MACHINE Position Checking keys Remarks 1. Condition of switches and potentiometers. Control 2. Volt and Amp display. Replace if faulty. panel 3. Warning lights 1. Check if there is air flow. Cooling If abnormal noise and no wind, to check the inside of the machine. - Page 13 DAILY CHECKING WIRE FEED ASSEMBLY Position Checking keys Remarks Pressing Check that it is not over tightened and is Leeds to wire slipping. not melted / distorted Check that there is no buildup of steel dust Clean the residue and check the reason and in the tube(residue) solve it.
