Mechanized Orbital Welding

Gas Management

& Auxiliary Equipment

Precision purging is essential for controlling weld quality, particularly Maintain Weld
when welding high-alloy, corrosion-resistant materials that are extremely
sensitive to oxygen in the welding process. Quality During the
OXY Process

Precise purging helps
you control weld quality
when using oxygen in
7 ppm (0.0007%) 27 ppm (0.0027%) 500 ppm (0.05%)
the welding process
* Compatible controller required. Contact your Praxair representative to discuss your application.
