What can the Triad Extreme Shelter make?

All of Miller Weldmaster’s welding machines are able to create strong seams in several applications. The Triad Extreme Shelter is specifically designed to be beneficial for the shelter and tent welding industries.

The machine can weld PVC, PE, and PP among other materials. The Triad Extreme Shelter in particular is useful for smaller production workshops, as the machine is portable and designed to be small and efficient. It is also a quiet machine, a feature your production employees will be grateful for. If your production floor does not have a lot of space to work with, a tabletop configuration of the Triad Extreme Shelter will still give you the results you need at a lower space cost.

Tent Welding with Triad Extreme Shelter

If you do tent welding or construct other shelters with industrial fabric, you know that you need a machine that can produce tight, smooth seams.
