The world's hottest hot bonder, the WichiTech HB-2 is a powerful, portable composite repair system that sets industry standards for ease of operation, safety, reliability and value. This durable system repairs metal, Kevlar, carbon, boron and fiberglass simply, safely and cost-effectively. HB-2 makes fast, flawless work of large or small repair jobs. The 35 pound USA-built unit is as simple to program as a microwave with its easy-to-read digital display and menu listed functions.

The custom made HB-2 is individually manufactured to your specifications. Select from a single zone unit up to a dual zone unit with two independent programmed heating zones, 20 amps each, and two individual adjustable vacuum zones or anywhere in between.

These twin features permit you to perform two independently-programmed cures simultaneously. Fail-safe protection is provided by the monitoring of multiple thermocouples, and audible alarms guard against temperature and vacuum conditions that could ruin the repair. Rugged field proven components shock mounted inside a tough, impact-resistant case mean years of reliable service from the HB-2 value engineered for first-time, every-time top of the line performance.
