Guide to buying an inverter welding machine

If you are looking to buy an inverter welding machine, there are some points that you should pay attention to before making a purchase. Whether for domestic use or for industrial use, the welding machine must be prepared based on the capabilities and according to the needs of the consumer. Welding is actually the act of sticking two similar metals together by melting both of them or melting another metal as a filler and The adhesive is two pieces of work. In electric arc welding, in fact, the electric arc created between the electrode and the metal of the work piece causes the electrode to melt (the electrode is actually the interface of sticking two pieces together).

The way the welding machine works is actually receiving alternating current (AC) with high voltage and low current intensity, and then converting it to direct current (DC) with low voltage and high current intensity instead. Different devices have the ability to produce intensity. They have different currents that the more the user needs a stronger weld and the more the device is used in industrial and workshop areas, the higher the ability to produce wing current in the device. The welding intensity we need is directly related to the thickness of the workpiece.

With the passage of time and the need to have accurate and reliable welding, welding machines are always progressing and modernizing, which has caused the variety of models and power of the machine, which must be checked before buying. The following tips will help you choose the right inverter welding machine:

Electric arc devices have different abilities in producing current intensity and the main distinguishing feature and noteworthy point is the intensity of current produced by the device. The intensity of the required current has a direct relationship with the intensity of welding and the thickness of the workpiece.

In simple words, the operation cycle is the time that the machine can weld continuously and after that it needs time to cool down. This parameter in welding machines is declared in terms of percentage, so that if the duty cycle of the machine is 100%, it means that this machine does not need any break for cooling and has the ability to weld continuously. Basically, the performance cycle is measured in a period of ten minutes. For example, if the operating cycle of the device is 50%, it means that in a ten-minute working period, the device needs five minutes to cool down. The amount of cooling required by the device increases with the increase in the intensity of the production flow. As the use of the device goes towards industrial and workshop, a higher performance cycle is required.

✅ Electric arc welding is actually an electric circuit with high current intensity, which if you touch this circuit and get in the middle of it, it will cause severe electric shock and even death. Therefore, it is recommended to pay attention to this point and use appropriate gloves during welding.

✅ The radiation resulting from the melting of the electrode can cause damage to the eyes and even skin burns; Be sure to use a mask and appropriate clothing. During the melting of the electrode, due to the burning of the protective layer, a significant amount of smoke and gas is created, which can cause breathing problems in closed environments.

✅ from this type of welding in environments where there is a possibility of fire and also due to throwing sparks during welding; Do not use near flammable objects.
