Witt has introduced a new gas analyzer to monitor and measure wrong gas mixtures to the torch.
The Germany based gas technology specialist says contaminated welds can be caused by a number of reasons and has therefore launched PA-O2/CO2, which is portable, compact and light in weight.
The company says: \\$quot;It only takes a small variation in the mixture to cause porosity. Not only is the weld appearance not good, it can also endanger the structural stability of the dynamically strained welded parts.
\\$quot;The source of gas supply is generally not important, be it a central bulk mixing unit or a ready made mixture, however no gas supplier can afford to rule out errors in the gas supply at the user\\$quot;s plant. That is why experts advise the use of quality control directly at the point of use.\\$quot;
