Precision Welding Technologies, Inc. Mar 08, 2002

Press Release Summary:

GTAW/PAW Ultimate Shield gas auxiliary and trailing shields proportionally redistribute single source of inert gas coming into standard welding torch into multiple gas paths throughout shielding system, so no secondary source of gas is required. Outer gas streams, which surround primary gas emanating from welding torch, provide layers of protection from atmosphere. Users can attain pure silver welds on all alloys outside of protective chamber.

Original Press Release:

GTAW/PAW Gas Auxiliary/Trailing Shields

The company is introducing its line of GTAW/PAW gas auxiliary and trailing shields. Highlighting the company's technology are the patented Ultimate Shield auxiliary/trailing shields. The devices proportionally redistribute the single source of inert gas coming into the standard welding torch into multiple gas paths throughout the entire shielding system, so no secondary source of gas is required. The outer gas streams, which surround the primary gas emanating from the welding torch, provide layers of protection from the atmosphere. Now it is possible to attain pure silver welds on all alloys, including reactive metals such as titanium, outside of a protective chamber.
