Oxyhydrogen Brazing FAQs

By Jacob Quamme

A senior consultant with Airserco, Jacob Quamme explains how the H2Oweld system works and why it makes sense. Airserco is the sole distributor of this innovative system in the US HVAC/R market. Offering decades of experience helping HVAC/R manufacturers improve line efficiency and quality, Airserco began partnering with H2Oweld in 2018.

We have brazed with oxy-acetylene for decades – why should we consider oxyhydrogen brazing?

H2Oweld uses state-of-the-art technology to produce a higher-quality braze, simplified operations, and increased safety at higher speeds. These factors translate to lower costs, better brand reputation, and improved employee satisfaction.

How does the system work?

H2Oweld uses distilled water and electricity to produce oxygen and hydrogen for fuel. All gas is produced on demand with very low pressure and no gas storage. That means no more managing or changing gas tanks, finding floor space for full/empty cylinders, or dealing with the associated vendor-management workload.  You benefit from improved uptime and greater safety since no gas is stored or under high pressure, as in brazing with compressed gases.

Finding and hiring good, experienced brazing technicians is very difficult right now – should I be worried about locating technicians who can use your system?

No! Unlike traditional systems, you get the exact same flame temperature every time, from every operator. So training new, inexperienced operators becomes very simple by comparison, and we provide comprehensive user training for every installation. Because H2Oweld uses a stoichiometric gas mixture – that is, the gas is mixed by the simple chemical reaction inherent in dividing the water into oxygen and hydrogen – it improves product quality by reducing variables. With traditional brazing, the operator must skillfully mix the gases at the torch every time it is started; any difference in flame temperature will affect the quality of the braze. Such variation is also present from one operator to the next.

Higher speed is typically the enemy of higher quality – how can you combine both?

Our system focuses the entire flame into a small area, putting heat only where you want it. It also allows the operator to heat the area quickly, thus reducing heat conducted farther down the pipe. These factors reduce the “heat zone” of pipe that is weakened by high heat, which lowers the risk of breaks/bursts in the pipe.  By minimizing the heated area, H2Oweld also reduces internal oxidation and minimizes damage to nearby components.

How is your technology different from any other oxyhydrogen brazing I have seen elsewhere?

Our systems are safer because the gas pressure is limited to under 10 psi. H2Oweld systems also use no acetone, which is a toxic additive that most competitors must use to make the technology work. However, acetone introduces a contaminant into the alloy which reduces quality. Furthermore, our systems are capable of brazing significantly larger pipes thanks to the high-output capacity of the gas generator. Most competing products cannot be used effectively for HVAC/R production, but ours can braze pipes up to 4” in diameter without any problems.
