Phoenix Welding Supply keeps Arizona welders productive with clean, consistent gases that protect weld quality and cut speed. We stock oxygen, acetylene, argon, CO2, nitrogen, helium, and custom mixes for MIG, TIG, flux core, and oxy‑fuel work. With six Arizona branches, a Phoenix fill plant, and the state’s only acetylene manufacturing, we back every order with dependable local supply and delivery.
Choose portable cylinders for field work or high‑volume cylinder packs and microbulk for production lines. Our team helps you size the right package for your usage and changeout schedule. We deliver across Arizona on scheduled routes and on‑demand service, and you can exchange cylinders at any of our branches. We also design and install bulk CO2 systems when your volume calls for it.
We support fabrication and manufacturing shops, construction and field services, schools, and training programs. From structural steel and pipeline work to classroom labs, we provide the right gases and delivery schedules to match your workflow. Beverage operations that need NF Grade CO2 and beer mixes are also part of our service footprint.
Not sure which gas is right for your job? For most carbon steel MIG, an argon and CO2 blend balances arc stability, spatter control, and bead appearance. TIG on stainless or aluminum typically calls for high‑purity argon, while certain stainless and nonferrous applications can benefit from helium blends for extra heat input. Running a cutting table or heavy brazing? Pair oxygen with acetylene for precise, fast cuts. Our specialists can review your process and recommend a cylinder or mix that meets your goals.
SURE-SHIELD is our line of argon based shielding gas blends engineered for consistent performance from the first arc to the last. These mixtures are produced for two, three, and four part formulas that include carbon dioxide, delivering stable arcs and uniform weld quality cylinder to cylinder.
Designed for shielded welding and cutting processes including GMAW (MIG), GTAW (TIG), FCAW, and Plasma.
