S.A.T. flux system: a game-changing brazing innovation

 

First Cut subsidiary, gas safety expert Gas Safety International (GSI), is revolutionising traditional industrial brazing with cutting-edge technology which enhances safety, quality and efficiency. This innovative solution is game-changing for industries reliant on high-performance brazing, including the automotive, white goods, storage (racking and shelving), fabrication and engineering sectors.

 

Traditional brazing comes with inherent risks, including gas leaks, inefficient fluxing, and safety risks due to high-pressure systems. Recognising this, GSI has added its revolutionary S.A.T. regulator, valve and torch to the innovative liquid fluxing system known as the D69. The S.A.T. flux system significantly reduces gas contamination risks and enhances gas welding and brazing efficiency, optimising productivity.

Already, the S.A.T. flux system has achieved extensive traction with a well-known white goods manufacturer - and with national wheelchair and motorcycle frame manufacturers.

 

Safe and efficient brazing - Peter Rohlssen, Managing Director of GSI, highlights the importance of safety in brazing operations: "Our goal is simple: to make brazing safer and more efficient - without compromising performance!" The D69 fluxing unit enriches flammable gas (for example, acetylene) with liquid flux by passing the gas through a reservoir, where it absorbs the liquid before reaching the torch for brazing. This process enhances brazing efficiency, improves joint quality, and operates under negative pressure to increase safety by preventing backflow, reducing explosion risks.

 

Negative pressure not only minimises workplace hazards, but also ensures compliance with international safety standards, making it a preferred choice for manufacturers prioritising worker safety and operational excellence. The GSI S.A.T. flux system also adheres to stringent industry compliance regulations, including ISO 2503, ISO 5175-2, ISO 5172, and SANS 3821.

 

The S.A.T. flux system addresses one of the most pressing concerns in modern manufacturing - downtime. With traditional brazing, equipment often needs to be de-pressurised for maintenance or reloading, leading to a halt in production and lost operational time. The S.A.T. flux system eliminates this - offering a continuous operation model, ensuring manufacturers can achieve peak efficiency without interruptions.

The S.A.T. flux system furthermore features a gas economizer with pilot flame, which ensures that the flow of gas and liquid flux to the torch stops when it is not in use, thereby saving product and time – and crucially, ensuring operator safety.

 

"In manufacturing, time is money. Every minute of downtime translates to lost revenue. GSI’s innovative S.A.T. flux system is about delivering a brazing solution not only enhances safety - but also optimises quality and operational efficiency. This is a game-changer for manufacturers requiring reliability and precision in their production lines,” says Ian McCrystal, CEO of First Cut.

 

GSI is an authorised service centre for the D69 fluxing unit. With the exception of the gas fluxing unit itself (which is US-manufactured and imported), the heart of the S.A.T. flux system - the S.A.T. valve - is ‘proudly local’, manufactured by GSI in Johannesburg. In close co-operation with Messer Cutting Systems small, medium and large gas welding and brazing torches are used.

 

GSI can also offer a full repair service, exchange units and spare parts as required.

Beyond the technology itself, GSI is committed to providing comprehensive training and support for customers adopting the new system. "We ensure that teams understand how to use it effectively, to transition smoothly to a safer and more efficient brazing process," Rohlssen concludes.
