A


gas increases productivity? Or improves quality? The experts at Air Products explain


exclusively to Welding World. It’s simple. Every year, you might well


be wasting welding gas through leaks from equipment, hoses and connectors, by using flow rates that are higher than the optimum and from having pre-weld surge. But with the Gastrak(R) service from Air Products, you could reduce your gas usage and therefore lower your costs and reduce your carbon emissions, just by cutting out the main causes of wasted gas.


Where you could be wasting gas Leaks Gas control equipment, hoses and connectors need to be regularly inspected and tested to make sure they’re safe and free from leaks. Many thousands of litres of welding gas are wasted every year due to leaks.
