REDUCE SHIELDING GAS USE BY 50% AND IMPROVE QUALITY WA Technology, after extensive laboratory and field testing, invented and patented products that reduce MIG shielding gas waste. Thousands are in use with fabricators reporting 40 to 60% reduction in gas use while improving weld start quality! Tried gas surge reducing approaches such as orifices mounted at the feeder or low pressure flow controls and welders were complaining or altering settings? We''ll show why the welders were probably right and how our patented products solve problems these other devices create!
