Featuring extra purge gas inlets and corresponding exhaust ports, PurgExtra® produces zero-color, non-oxidized weld roots. Operators can purge normally at first and then when conditions are correct, introduce additional gas at high flow rates to create faster purge and more efficient removal of unwanted gases. System is designed for weld purging of Titanium in particular, as well as Ultra High Purity stainless steel joints, corrosion resistant alloy welding, and duplex steel joints.
