Training and Technical KnowHow: How nexAir Empowers Welders to Work Smarter

Welding skill comes from experience, but experience alone doesn’t always teach you the most efficient way to do things. Welders who understand the science behind their craft make better decisions about gas selection, equipment settings, and technique adjustments. They troubleshoot problems faster and produce more consistent results. nexAir bridges the gap between what welders learn through repetition and what they need to know to work at their best.

Understanding Gas Behavior Changes How You Weld

Most welders know which gas to use for common applications, but fewer understand why those gases work the way they do. Argon flows differently than helium. CO2 produces a different arc than argon-CO2 blends. When you understand how each gas behaves in the weld pool, you can make smarter choices about mixtures for unusual materials or challenging positions.

A welder who only knows “use 75/25 for steel” gets stuck when that mix produces too much spatter or insufficient penetration. A welder who understands how argon affects arc stability and how CO2 influences penetration can adjust the blend to match the challenge. We help welders build that deeper understanding so they’re solving problems instead of just following procedures that might not fit.

Equipment Settings Make More Sense With Context

Voltage, amperage, wire speed, and travel angle all interact in ways that aren’t obvious until someone explains the relationships. Welders who grasp these connections can dial in settings for unfamiliar applications instead of relying on trial and error.

nexAir teaches welders why certain settings produce certain results. When you know that increasing voltage widens the bead while increasing wire speed adds reinforcement, you can predict what adjustments will fix a problem before wasting material. That knowledge speeds up setup, reduces waste, and builds confidence for work outside the usual routine.

Troubleshooting Gets Faster With Systematic Thinking

Weld defects have identifiable causes, but finding them requires knowing where to look. Porosity might come from contaminated base metal, insufficient gas coverage, or a leak in the system. Undercut could be too much heat, wrong torch angle, or excessive travel speed. Welders trained to diagnose problems systematically work through potential causes in logical order instead of changing random variables.

We teach welders to read the symptoms and connect them to root causes. Consistent porosity along one edge suggests directional gas coverage problems, not contamination. Intermittent spatter points to wire feeding issues rather than gas mixture. Building this diagnostic skill turns mysterious problems into fixable issues with clear solutions.

Continuous Learning Keeps Skills Current

Welding technology evolves constantly. New filler metals, updated processes, and different gas mixtures create opportunities for better results, but only if welders stay current. Shops that invest in ongoing education benefit from new techniques and materials while competitors keep doing things the same old way.

Better welding comes from better understanding. nexAir helps welders Forge Forward by building the technical knowledge that turns experienced operators into problem-solvers, backed by our expert KnowHow™ from training welding professionals across every industry.
