A set of argon arc welding equipment including welding power supply, welding torch (torch) a set of argon bottle (or argon supply line), argon meter (argon decompression flow meter), the installation method is shown in the attached figure. The figure is to 200A argon arc welding equipment as an example.
Torch is divided into air-cooled and water-cooled two kinds, when the welding current is less than or equal to 200A, can be used when the air-cooled torch, that is, the torch is only connected to the torch can be passed with argon composite welding cable, welding cable terminal at the other end of the output of the welding machine connected to the positive pole, argon tube connected to the welder panel of the argon gas output port. ? If the welding current is relatively large, it is necessary to use water-cooled welding torch, the head of the torch at this time and more than a set of cooling circulating water piping, water pipes and cables tied into a bundle of use, the other end of the water pipe connected to a cooling circulating water tank (not in this picture).
Argon meter screwed directly on one end of the argon bottle, the other end of the gas pipe to the back of the argon arc welding machine version of the argon inlet, the welder has a solenoid valve, through the torch handle on the switch to control the argon on and off.
Now the welder will be connected to the power supply, the welder ground wire to the workpiece, connected to the torch cable and gas pipe, connected to the gas bottle, argon meter, gas pipe, open the argon bottle, adjust the flow of argon meter in 15-20L/min, turn on the power supply, adjust the welding current, you can try welding.
