Oxyhydrogen Brazing FAQs
By Jacob Quamme
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.
Evacuation & Charging FAQs
By Jacob Quamme
What does Vacuum Evacuation and the refrigerant charging process entail?
Vacuum evacuation is when moisture, air, and non-condensable gases are removed from a circuit by pulling a vacuum on the system. To do this, a vacuum pump is used to create a negative atmospheric pressure inside a circuit allowing molecules to evacuate the system. This process is necessary to ensure HVAC and refrigeration systems and equipment are performing optimally and to prevent failure of the system. After a system is tested to make sure all unwanted molecules are evacuated, (using a process known as Decay/Rise test) the system is charged with refrigerant that is in a liquid state.
How do I maximize my evacuation efficiency?
Any obstacles in the path of molecules trying to evacuate the HVAC/R system slow the process. Here are seven actions you can take to increase HVAC/R evacuation efficiency:
- Minimize the number of connections, orifices, values etc. between the vacuum pump and the circuit
- Minimize hose lengths and maximize hose diameters
- Reduce the use of elbows or sharp angles in the hoses
- Connect to high and low-pressure sides
- Make sure your pumps are serviced regularly
- Maximize the inside diameter of any connections
- Make sure your system is sealed and not leaking
Do we offer products to support hydrocarbon refrigerants?
Yes. We offer hydrocarbon refrigerant products that cover classes A1, A2, A2L, and A3. We take great care to comply with the county, state, and federal regulatory requirements of each of our customers and oftentimes partner with local engineering firms to ensure all regulations are met.
Do you offer machines and options to meet my specific budget?
Yes. We have many different product levels to service both high and low volume needs. We offer customized solutions based on your business’ individual needs and budget. We always maintain competitive prices in comparison to competitors.
Do you offer maintenance and support services?
Yes. We offer both repair and support services for our parts and equipment. We have service technicians available, as well as remote support available for immediate troubleshooting.
