The welding gas saver "Eco Plus/Eco Float (compatible with CO2, Ar, and MAG)" saves unnecessary gas released in the hose during welding operations, especially at the start (the moment the torch switch is pressed). It can reduce wasted gas by up to 1/6 depending on the conditions, leading to significant cost savings! With a maximum flow rate of 50L/min, it can be used even in high-flow environments like shipyards. It can be easily attached to the current regulator and flow meter with just one wrench, eliminating the need for equipment replacement. (The Eco Float integrates the flow meter (25L or 50L) and Eco Plus.) Companies that frequently weld in multiple locations, repeatedly turning the torch on and off, or those performing back seal welding using the high-cost gas Ar can expect substantial savings. 【Features】 ■ Usable even at high flow rates ■ Reduces wasted gas by up to 1/6 ■ Saves unnecessary gas released beyond what is needed ■ No need for equipment replacement ■ Easy installation with just one wrench For more details, please contact us.
