When implementing the topic of “welding gas mixtures”, the highest accuracy may be important for quality and/or cost reasons. This is where the gas mixers from LT GASETECHNIK show their special strength.
Panel production plants and profile welding with gantry welding machines use gas mixtures of Ar, CO2, and Ar, CO2, He. Helium, in particular, is an expensive and scarce noble gas in which the highest mixing precision quickly pays off. The LT gas mixers used for these projects guarantee a deviation of ≤ ± 0.2 vol.%. In contrast to the previously used gas mixers of a market competitor with ± 2 vol.% deviation, this means an improvement of 90%.
In this project, the gas mixers installed on the portals were connected to the machine control system with Beckhoff interface. In this way, the respective welding machine can select the appropriate recipe and the gas mixer sets the required gas mixture fully automatically. This not only saves money, but also always produces quality with the right welding gas.
Of course, this type of gas mixer can also permanently document the individual gas consumption and analyze and document the mixed gas quality.
