550 Weld Cleaner
The definitive choice for professionals who need versatile, high-performance weld cleaning machines built to tackle heavy stainless steel and tough welds with unmatched reliability.
TIG Brush 550 — Power, Versatility, and Reliability for Tougher Welds
The TIG Brush 550 is the ideal electrochemical weld cleaner for professionals who need extra power to handle dirtier and more demanding welds. Engineered for mid to heavy-duty applications, it delivers peak performance while remaining the most economical option in its class.
This advanced unit supports electrochemical cleaning, passivation, surface finishing with a wider brush, stainless steel polishing, and even branding and marking. Its intelligent design incorporates patented Dynamic Power Transfer and a true 100% duty cycle, ensuring consistent, high-performance output without the need for downtime.
Easy to use, safe, and reliable, the 550 offers a long-term solution for effectively cleaning and passivating stainless steel – while also protecting against future corrosion.
What TIG Brush Model Do I Need: TBE or TBX?
Choosing the right TIG Brush model depends on the power supply in your region:
TBE Models (Dual Voltage 110V–230V):
Ideal for regions where both 110V and 230V power supplies are commonly used. The TBE series automatically adapts to different voltages, making it perfect for international projects, mobile applications, or areas with mixed infrastructure.
TBX Models (Single Voltage 220V–230V):
Best suited for regions that operate exclusively on 220V–230V. These models are optimised for consistent, high-performance operation on single-voltage systems.

Kit Options
550 Slimline Kit
The 550 comes standard as a Slimline PROPEL Kit, using the latest patented push-in brush (PIB) technology which is more resistant to corrosion and more resistant to seizing. In fact, PIB precision engineering uses fine tolerances so the brush can be easily pushed in and stay in place, providing the user with an application tool that is incredibly reliable and easier to clean and maintain.
The 550 Slimline Kit also includes all the essential consumables you need to start cleaning welds including the 550 control unit, Slimline application tool with 4M/13’ cable, ground cable, 10 pack of Push-In brushes, 1L/Q weld cleaning fluid, 1L/Q neutralising fluid, PPE, fluid jar and spray bottle, Instruction Manual and Quickstart Guides.
The 550 is also compatible with other TIG Brush application tools, such as the LokWand, the Classic Wand, PROPEL Torch and the Flexi Handle. All alternate application tools are available as add-on purchases.

What more can you ask?
Whether you’re dealing with TIG, MIG or MAG, the 550 delivers a quality finish and a safer alternative to highly toxic pickling acids, or arduous abrasive processes.The 550 utilises a specifically focused adaptation of the 700 series design, to align its performance with Ensitech’s latest technological advance, the Slimline PROPEL. As you would expect, this gives you exceptional results consistently and reliably, delivered by our proven combination of heat, electricity and chemistry. The TIG Brush’s on going innovation and patented power delivery system gives you peace of mind in the knowledge that you have achieved the industry’s highest level of passivation in a fast but safe way.
Next-Generation Comfort, Engineered for Professionals
The TIG Brush series is designed with a deep understanding of real-world welding environments, where performance and ergonomics are equally critical. Each unit is engineered to deliver maximum output efficiency while ensuring operator comfort during extended use.
Compact in form for optimal portability across job sites, the unit features streamlined control interfaces that reduce setup time and learning curves. A low center of gravity and bottom-weighted chassis enhance stability during operation, eliminating tip-over risks in workshop or field environments.
From design to execution, every detail of the TIG Brush is focused on improving user workflow, reducing fatigue, and delivering consistent, high-quality results – job after job.
To ensure a reliable and safe experience, the TIG Brush features a unique variable power supply, enabled by our patented Dynamic Power Transfer.
What is Dynamic Power Transfer?
The TIG Brush uses a conductive brush with extremely low resistance, meaning it requires very little voltage (or pressure) to push current through. In fact, one of the challenges with this design is that it becomes difficult to limit the current, which can cause the brush to run too hot.
As the brush wears down over time, its resistance decreases even further – potentially making current control even more unstable.
Recognising this, Ensitech developed Dynamic Power Transfer – a patented technology that powers the TIG Brush’s variable power supply. This intelligent system adjusts output in real time, ensuring a consistent, safe, and reliable user experience, regardless of brush wear or surface condition. It’s one of the core innovations that sets TIG Brush apart.
100% Duty Cycle – No Downtime. No Compromise.
Some manufacturers cut costs by using lower-grade components that can’t handle continuous operation. To prevent overheating or damage, these machines rely on a limited “duty cycle” – meaning they must be shut down periodically to cool off. Not the TIG Brush.
Built with premium components and engineered for endurance, the TIG Brush operates at a true 100% duty cycle. That means you can run it continuously, without pauses or cooldowns – no matter how demanding the job.
No rest. No waiting. Just uninterrupted performance, shift after shift.
