1 将机器设备放置于通风条件良好地点，以免冷却系统失效。
2 焊机输入电源线接在三相AC380V的配电箱上，将机壳用导电截面积不小于6mm2的导线可靠接地，方法是自焊机背面的接地螺丝处连接到接地装置
3 将送丝装置的控制电缆和焊接电缆分接在焊接电源的正极和焊接电源控制线插座上。
4 用线把焊机的负极连接到要焊接的工件上。
5 将气体调节器的加热电缆接至焊机后面板加热电源输出插座，送丝装置的气管接到气体调节器的输出端上。
6 将焊枪用内六角接到送丝装置上，装上焊丝，并且选择与焊丝直径相应的送丝轮和导电嘴。

完成上面的操作后，你就可以合上焊机面板上的空气开关，进行二氧化碳保护焊作业了。

An equipment will be placed in ventilation conditions are good locations to avoid cooling system failure. \ \
Two welders input in the three-phase power lines to the distribution box AC380V, will be conductive chassis cross-sectional area of not less than 6mm2 grounding wire reliable method since the grounding screw on the back of the welding machine connected to the grounding device \ \
Three will be sent to the control device wire welding cables and cable connections in the positive electrode welding and welding power socket on the Line of Control. \ \
Four lines with the anode connected to the welding machine to weld on the workpiece. \ \
Five gas regulator heating cable access panels to welder after heating power output sockets, wire feeding device tracheal gas regulator from the output on. \ \
Six torch will be received by the hexagonal wire feeding device, fitted with wire, and the selection and the corresponding wire diameter wire feeding Ferry and conductive mouth \. \ \

Completion of the above operations, you can close the air welder panel switch, the CO2 welding operations. \ \
