Supplier of Specialty Gases to the Metal Working Industry in Indianapolis PurityPlus® specialty gases and equipment are in high demand for today’s ever more refined specialty metal working, and American Welding & Gas, Inc. is the company supplying all of Indianapolis. Many Indianapolis jobs in specialty welding and cutting call for gases that satisfy minimum purity standards, with certificates of analysis and conformity. Analytically correct gases with defined impurity specifications have always been prime specialty gases and incredibly useful regardless of whether the need is for high-purity Argon for Gas Tungsten Arc Welding (GTAW or “TIG”) or close-tolerance multi-component gas mixtures of Oxygen, Carbon Dioxide, Helium, and Argon for Gas Metal Arc (GMAW or “MIG”) and Flux Cored Arc Welding (FCAW). Contemporary American manufacturing – metal working in particular – regularly employs the very lasers that at one time, back in the ’60s, were looked up as toys or the stuff of fanciful movies like “Goldfinger.” Precision laser cutting and welding processes must have gases of the finest purity and most exacting composition, whether they’re the now relatively ubiquitous carbon dioxide, nitrogen, and helium mixtures or specialty purpose-blended mixtures produced by PurityPlus®. And PurityPlus® Gases are but one component. Metal working users need correct gas pressures and flow rates. PurityPlus® gas apparatus, among them precision high-flow, two-stage regulators and flow meters, enable the constrained tolerances these manufacturing applications require. Beyond that, the PurityPlus® specialty gas equipment line includes customer stations that keep an eye on gas cylinder content. This purpose-built equipment can automatically “switch over” cylinders that are almost empty to completely filled cylinders absent any shut-down and change-out time, so the procedures can keep going.
