Avoid contaminated welds by using a portable, compact and light weight PA-O2/CO2 gas analyser to monitor and measure the gas mixture supplied to the welding torch: it also has built in alarm functions
Contaminated welds can be caused by a number of reasons Witt, the Germany based gas technology specialist, has introduced the portable, compact and light weight PA-O2/CO2 gas analyser to monitor and measure a cause often overlooked - the wrong gas mixture to the torch

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.
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 completely rule out the chance of errors in the gas supply at the users plant.
That is why experts advise the use of quality control directly at the point of use.
By using the Witt PA gas analysers, the CO2 and O2 concentration can be measured and monitored as often as required or even continuously.
This will ensure that the gas mixture at the point of use is correct, helping improve quality, reducing component rejects and project delays.
Used with the Witt Logger Software the operator is able to record the last 100 measurements for use as quality control documentation.
Only the smallest sample is needed to record a reading, the results are fast.
It is easy to use and has a multilingual menu guide.
If the gas contents exceed the set minimum or maximum limits, an alarm is activated.
These analysers can be supplied with either an inclined or a vertical display.
A separate tabletop printer is also available as an option.
The voltage requirements are 230V AC, 110V AC or 24V DC.
They each weigh 3kg and are very compact measuring 145mm x 105mm x 200mm.
