Worldpoly PolyForce24 Track Fusion Machine. Manufactured in Australia. Arguably the fastest, safest, most consistent butt welding machine available. Thanks to 3 years of research and development with Bosch Rexroth and Worldpolys’ nearly 60 years of PE pipeline experience, every weld is the same. PolyForce24 Track gives you complete control over welding by virtually removing operator variables. Includes all features in the PolyForce24 Trench, as well as three speed rubber tracks, cordless and corded remote control and external pipe lifters.
