Ducting, Ventilation and Hose Welding Machines

Spiral and flexible ducting products are in demand for a number of industries including agriculture, building, mining and ventilation.

Variable Sizes

Miller Weldmaster welding machines offer variable wire diameter and wire pitch. We have the machine for any size ducting, ventilation or hose.

Stronger Seals

In addition to offering multiple diameter options, our machines can add wire reinforcement with wear strips to help eliminate air loss in mine ventilation and to produce air-tight seals.

Save Labor Costs and Increase Production

Automating the process helps boost efficiency and save time and labor. Our welders reduce operator handling with fabric unwinds and ducting take away built to any length. We offer a fully automated system that can weld panels together, create t-tape, apply to tube, grommet and cut to length.
