Self-propelled hot air welding machines for multi-function jointing: rope welding, hemming, butt-joint welding and overlap welding on coated fabrics. The TOP4500 multi-function series runs an imported heating element with a brushless fan and a digital constant-temperature control system, and adds a guide wheel for following seams and edges.

In the field

One machine covers rope, hem, butt-joint and overlap seams, which keeps a fabrication shop from switching welders between jobs.
