Specialized automated machines and manual orbital welders, plus advanced laser cutting and laser welding systems, run best on clean, stable gas. Phoenix Welding Supply provides UHP gases that protect weld chemistry, keep optics clean, and deliver repeatable results. If your tolerance is tight, your purity cannot drift.
Arizona buyers also get local responsiveness with global strength. As part of Air Water America’s Industrial and Packaged Gas Division, we combine six in-state branches and a Phoenix fill plant with worldwide logistics and production resources. That means dependable supply, fast delivery, and a team that understands high purity handling.
We source and deliver these UHP grades in 300 cf cylinders:
UHP Hydrogen supports semiconductor fabrication of microchips and electronics, and is also used in the fuel cell industry for vehicles and backup power. Note: We do not offer medical grade gases.
Orbital GTAW (TIG): UHP Argon and UHP Helium enable stable arc starts, smooth bead appearance, and reliable penetration on stainless steel, nickel alloys, and titanium. Backpurge packages benefit from UHP Nitrogen or Argon to control oxygen and moisture inside tube or pipe.
Laser cutting and welding: UHP Nitrogen, Oxygen, and Argon support clean edges, higher cut speeds, minimal dross, and bright welds. Consistent purity helps maintain beam quality and uptime while protecting optics and mirrors.
Semiconductor and energy: UHP Hydrogen is used in wafer processing and deposition, and also supports fuel cell development for vehicles and stationary backup power.
Consultation is simple. We confirm your process, consumption, and purity specs, then recommend cylinder or microbulk options sized to your run time and change-out plan. Our delivery fleet covers Arizona from Flagstaff to Sierra Vista with scheduled routes and on-demand service when you need it. Our team can also review regulators, hoses, and purge routines to help protect purity from the cylinder to the weld or cutting head.
Since 1953, Phoenix Welding Supply has supported Arizona industry with local inventory, knowledgeable people, and dependable service. With six branches and a Phoenix fill plant, we bring UHP capability close to your floor so you can stay productive and compliant. Our partnership with Air Water America strengthens supply security and accelerates access to innovations that improve purity, safety, and efficiency.
