What does it mean to mark ws 250a on welding machine

The model identification of the welding machine is composed of two parts; The prefix indicates the type of welding machine (which can also be understood as a function), and the suffix indicates the current level;

Such as: WS-250; The prefix is"ws", the suffix is"250";

WS-250: DC TIG welding machine (built-in DC hand arc welding function), rated output current 250A;

The naming of the welding machine is clearly stipulated in the national standard, see the screenshot below and you will be very clear about the meaning of the name:

The welding machine superscript WS-250A refers to the model and rated current of the welding machine. Among them, WS represents the model of the welding machine, and 250A represents the rated current of the welding machine is 250 amps.

A welder is a device used to weld metals to join two or more metal materials together by heating them to a molten state and then cooling them to solidify. The rated current of the welding machine refers to the maximum current that the welding machine can withstand under normal working conditions.

A current rating of 250A means that the welder has a maximum current of 250 amps in normal working order. Amps are a unit of electric current that indicates the amount of charge passing through a conductor per unit time. The magnitude of the rated current determines the welding capacity of the welding machine, i.e., the maximum current that can be supplied while welding.

For the WS-250A welder, it has a current rating of 250 amps, which means it can provide a maximum of 250 amps when welding. This means that the welder can be used to weld larger metal workpieces, as the higher current can provide higher heat, making the weld stronger.

However, it is important to note that the rated current of the welder does not mean that the welder will provide that current all the time it is working. In fact, the current output of the welder can be adjusted according to the welding needs. In actual use, the current output of the welding machine can be adjusted according to factors such as the type, thickness and welding position of the welding material to achieve the best welding effect.

In a word, the WS-250A welding machine is a welding machine with a model of WS-A and a rated current of 250 amps. It has a large welding capacity and is suitable for welding larger metal workpieces. In practical use, the current output of the welding machine can be adjusted according to specific needs to obtain the best welding results.

250 and 315 refer to the maximum broad rock welding current for this welder. There is no requirement as to how big the electrode to use.

The difference between the electric welding machine 250 and 315.

1. The rated current is different

The rated current of the output is different, and the corresponding sizes are 250A and 315A respectively according to the mark.

2. The power consumption is different

Due to the difference in rated current, it will appear to consume more power when working 315, and on the contrary, 200 power consumption fiber cultivation amount is the smallest. <>

The knob is opened to this is manual welding, that is, welding rod.

This is a gas test, and the solenoid valve is open here, and the welding torch has been gasing.

The remaining 3 are argon arc welding, which may be the choice of DC welding pulse welding frequency, and you should be clear about what function you try.

The first gear is electric welding; The second gear is gas detection; The third gear is the 2t (2 steps) function of argon welding (press the gun switch to work, and the loose gun switch arc breaking machine stops working); The fourth gear is the 4T (4 steps) function of argon welding (press the gun switch to start the arc "adjust the visible size change of the starting current", loosen the gun switch welding "adjust the visible current change of the welding current", and then press the gun switch to close the arc "adjust the arc closing current visible current size change", and then release the gun switch to break the arc "the machine stops working"); The fifth gear is the reversing function of argon welding (press the gun switch arc current, release the gun switch welding current, then press the gun switch arc current, and then release the gun switch welding current) and so on), using the gun to break the arc.

This is a manual tungsten argon arc welding machine with pulse function, the maximum output current is the tungsten argon arc welding, S represents the operation mode manual, M represents the pulse 160 means the maximum output power is 160A. The detailed expression is shown in the figure below
