Construction welding and cutting made easier: Acetylene, argon and more from nexAir

Welding and cutting on construction sites is unpredictable. One day you’re joining steel beams for a commercial frame, the next you’re making emergency repairs on equipment that broke down mid-project. The gases you’re using need to handle whatever gets thrown at them, and you can’t afford to have the wrong mix slow you down or compromise the quality of your work.

Acetylene for Heavy Cutting Jobs

Acetylene is the go-to choice for oxy-fuel cutting when you’re working with thick steel. It produces the hottest flame of any fuel gas, which means you can cut through heavy structural steel faster and cleaner than with alternatives. If you’re doing demolition work or cutting through rebar and I-beams, acetylene gives you the temperature and precision you need without wasting time.

The flame control you get with acetylene is hard to beat too. When you’re working on a busy site with limited space or awkward angles, being able to adjust your flame quickly makes the difference between a clean cut and a mess you have to fix later. We supply acetylene in multiple cylinder sizes, so whether you’re running a small crew or a large-scale operation, you have the volume you need without paying for more than you’ll use.

Argon and CO2 Blends for MIG Welding

MIG welding is the standard for most construction welding applications, and your shielding gas choice directly affects the strength and appearance of your welds. Pure argon works well for aluminum and non-ferrous metals, but most structural steel welding calls for an argon-CO2 mix. The CO2 increases penetration and gives you a hotter arc, which is exactly what you want when you’re welding thick sections of steel that need to hold serious weight.

We’ve out our expert KnowHow™ to work with welders who were using generic mixes and running into problems with spatter, weak penetration, or rough-looking beads. After switching to a blend designed for their specific steel type and welding position, they saw immediate improvements..

Oxygen for Cutting and Heating

Oxygen isn’t just a supporting player in oxy-fuel setups. It’s essential for the cutting process itself, feeding the combustion reaction that melts through metal. The purity of your oxygen affects how clean your cuts are and how fast you can move through material. Low-quality oxygen leads to rough edges, excess slag, and more grinding work after the fact.

Oxygen is also useful for heating and bending operations when you need to shape structural steel on site. Having a reliable supply keeps you from waiting around when a piece needs to be modified or adjusted to fit properly.

Gas Delivery That Keeps Up With Your Schedule

Construction projects move fast, and your gas supply needs to keep pace. We deliver across the Southeast and work directly with contractors to set up schedules that make sense for your timeline. Running low on cylinders? We swap them out. Need to adjust your order because the project scope changed? We handle it without the back-and-forth.

Our territory managers know construction work doesn’t follow a predictable schedule. Equipment breaks, weather delays happen, and scope changes are part of the job. We help you Forge Forward by staying flexible and keeping you supplied no matter what comes up. Contact nexAir and let’s set up a delivery plan that works for your projects.
