Page 4: Safety Warning
SAFETY WARNING The safety notes listed in this manual is to ensure correct use of the machine and to keep you and other people from being hurt. The design and manufacture of welding machine considers safety. Please refer to the safety warning listed in the manual to avoid accidents. - Page 5 Please follow the rules below to avoid heavy accidents. Never use the equipment to do other things but welding. Follow related regulations for the construction of the input-driven power source, choice of place, usage of high-pressure gas, storage, configuration, safe-keeping of workpiece after welding and disposal of waste, etc.
- Page 6 Keep hot workpiece after welding away from flammable gas. Do move away the combustible around when weld the dooryard, ground and wall,. The wire connection of base metal should be as close to the welding place as possible. Never weld those facilities with gas pipe or airtight slot. Put fire extinguisher around the welding area to prevent fire.
- Page 7 Never put the cylinder under high temperature or sunshine environment. Keep your face away from the gas cylinder exit when opening it. Put on the gas shield when it is not used. Never put the torch on the gas cylinder. The electrode can not meet the gas cylinder. Any touch of the switch part will cause injury, please note the following.
- Page 8 Electromagnetic interference needing attention. It may need extra preventive measures when the equipment is used in particular location. Before the installation, please estimate the potential electromagnetism problems of the environment as follows. a) Upper and lower parts of the welding equipments and other nearby power cable, control cable, signal cable and phone cable.

Page 9: Machine Description
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 inverter power supply theory and components. Inverter gas-shielded welding power source utilizes high-power component to transfer 50/60Hz frequency up to 100KHz, then reduce the voltage and commutate, and output high-power voltage via PWM technology. -
