Welding inverters help improve weld quality and reduce operating costs. But one has to select the right kind of tungsten to get the maximum benefit from a welding inverter. Experts used to recommend the use of pure tungsten if you were using a welding inverter, but today ""rare earth"" tungsten is favored over pure tungsten. The use of rare earth tungsten has been made possible by new technologies developed in the filed of welding. The choice of rare earth tungsten depends on various factors such as the kind of welding inverters one is using and the metal which needs to welded.

Welding inverters often cost more than traditional welding equipment. Sometimes the difference could be as much as 100 percent. This often acts as a deterrent for many manufacturers, especially the smaller ones, who might not be able to afford a welding inverter.

But inverter technology can save as much 25 percent of your costs. There are other advantages also, such as better control over depth-to-width ratios. Welding inverters help one to weld at a much faster speed. It also reduces the time spent in welding, and cuts down on gas and tungsten consumption.

There are a number of models of welding inverters available on the market. Some companies are also ready to provide customized welding inverters to suit your requirements. There are certain technologies, easily available on the market, which help one to go for very light welding inverters. They are portable and can be easily accommodated in your workshop or factory. But sizes may vary according to the capacity of a welding inverter. So does the price. You choose one which suits your need. If you are not sure which one to go for, search web sites that provide detailed information about products of various companies manufacturing and selling these kinds of inverters.
