The Plastic Fusion Pro Unit is BETAG’s top-of-the-line welding unit. The unit performs several functions. It has an integrated tacker with three power levels. These can be adjusted for different plastics. For the fusion function, there are three modes available depending on the desired options. With the internal compressor, the temperature can be preset and the real temperature can be seen on the display. The Fusion Pro can achieve a higher temperature at a lower air volume, which is the key to achieving a good bond. The Fusion Pro can also connect to an external air source, so the user can increase the air volume if desired. On some repairs, a higher air volume is desired as this can speed up the bonding process. The unit can also use nitrogen to perform nitrogen welding.
