The FX100 duct welding machine is an automated hot air welding system engineered to produce continuous spiral seams in flexible ducts, reinforced hoses, and industrial ventilation tubing. Designed specifically for manufacturers operating in HVAC duct manufacturing and industrial airflow markets, the FX100 addresses one of the most persistent production challenges: creating long, airtight helical seams with consistent strength and repeatability.
Production engineers and plant managers face increasing pressure to improve throughput while maintaining duct seam strength and airtight performance. Manual or semi-manual processes struggle to keep pace with reinforced materials, long seam lengths, and rising quality expectations. The FX100 is purpose-built to solve these challenges through automation, delivering controlled hot air welding during continuous duct formation.

The FX100 duct welding machine is an automated system designed to weld flexible ducts, industrial ventilation hoses, and reinforced tubing using continuous hot air welding. Unlike flat welding systems, the FX100 is engineered specifically for round and spiral duct geometries, where seams must follow a precise helical path.
Manufactured by Miller Weldmaster, the FX100 integrates material handling, spiral forming, and welding into a single automated process. This focused design allows manufacturers to produce strong, airtight duct seams at production speeds that are difficult to achieve with manual methods.
Automating flexible duct welding presents unique challenges that differ significantly from flat fabric or sheet welding. Spiral seams must remain consistent over long lengths, often through multiple material layers, while maintaining airtight integrity.
Reinforced ducts introduce additional complexity. Embedded supports, scrim layers, or wear strips require precise heat control to ensure proper fusion without damaging the material structure. These factors make general-purpose welders ineffective for ducting applications.
The FX100 automates the duct welding process by synchronizing material forming and hot air welding into a continuous operation.
By maintaining constant welding parameters, the FX100 delivers repeatable seam quality regardless of duct length, improving both speed and consistency.
Hot air welding uses precisely heated air to soften thermoplastic materials before applying pressure to fuse them together. Unlike tapes or adhesives, this method creates a true molecular bond between layers.
For example, in an HVAC duct carrying conditioned air, a hot air welded seam resists leakage under pressure far more effectively than bonded alternatives. This results in improved system efficiency and longer product life.
The FX100 is engineered to handle the demands of reinforced ducting and industrial tubing without interrupting production.

Automation with the FX100 changes how labor is deployed on the production floor.
These gains help manufacturers scale production while controlling labor costs and quality variability.
Demand for flexible ducting and industrial ventilation products continues to rise alongside growth in HVAC, data centers, and industrial air handling. Manufacturers are under pressure to deliver higher volumes without sacrificing quality.
Automation in HVAC production is becoming a competitive necessity rather than a future consideration. Systems like the FX100 align with broader ducting industry trends by enabling scalable, repeatable manufacturing processes.
