Root Twister TFPV6082, 8 x 20, 60 kW Fine Plasma
Root Twister TFPV Series, with Bevel Cutting

The Root Twister TFPV Series cutting machines feature the Twister Fine Plasma Torch with Bevel Cutting Head. (See the News Release) Using the bevel cutting head, one or two pass cutting can be used to produce beveled edges for welding.

TFPV will dramatically improve efficiency of the cutting process, include welding preparation, and it can reduce product cost and time for weld groove.
