You'll get big performance from the industry's smallest, most powerful and economical hot bonder for curing composite repairs. This handheld unit performs well from the workbench to the tightest, spots, the highest places.
The HB-1 is a full featured bonder. The HB-1 can be seamlessly networked, enabling the interconnection of multiple HB-1's to support extra large or very complex repairs.

Compact and durable, the 3.5 pound HB-1 repair system has all of the features of much larger and more expensive units: four active thermocouple inputs, audible alarm and safety devices and the ease of programming that is a signature of WichiTech bonders. Set to go with its own standard vacuum line and heating blanket, all it needs is a vacuum source or shop air with venturi to do the biggest or smallest jobs quickly and efficiently.
