A device that provides the electric current to conduct welding Is known as a welding power supply. It can be something as normal as a car battery or as complex as a high frequency inverter that uses a computer for control. Inverter welders are designed to cope with high power welding and use a switched mode power supply that can convert the AC power to DC and vice versa and can effectively produce the level of voltage and current that is needed for the type of welding being performed. They have a switching frequency of 10 kHz but can be higher but that may require more complex components but will decrease the bulk of the transformer used to covert. It also has features such a power control and protection against overloading and in general provides a better control of variants and is also more efficient. Certain inverter machines also have a microcontroller that allows changes to be made through the software in real time and allows the implementation of features such as welding current and current densities required in the process. It is also possible to add new features through updating the software rather than buying a new welder altogether.
Inverter welders are the result of latest technological advances and use silicon-based technology rather than the traditional copper/aluminum transformers. When they were first introduced into the market there were quite a few problems but they have been rectified to make these welders more cost effective and reliable. One of the main advantages is that the inverter welder has a small size and is so compact that it can be easily carried around like hand held portable yet lightweight machine. They use smaller transformers which gives them a sleeker look as compared to traditional welders that are difficult to carry and fit in compact places. They also consume much less power and can even be plugged into the household current which allows for lower electricity bills. This also eliminates the need for generators which would also add to the cost of welding. These welders also work equally well on impure power reducing bad welds. You can tune them according to your needs as the output power can be adjusted to any level. It is the ideal solution for all types of welding’s; you can operate it on a lower voltage and allows financial savings as well as they are less expensive than traditional welders to install and operate. They also help reduce the damage to the base material and better results can be achieved through fine tuning.
