Accessories
ThermaView™
The ThermaView™ diagnostics package is a microprocessor based graphical software that gives mill operators and maintenance technicians a constant display of weld parameters in addition to easy-to-use trouble shooting indicators. A powerful preventative maintenance tool, ThermaView™ provides indication of welder status and operation.
Tooling
Genuine Thermatool™ tooling including induction coils and impeders ensure full weld power output and reliable operation. Thermatool™ CFI induction coils are proven, standard designs for long-life and optimized matching between the welder and the range of loads presented by different diameter and wall thickness combinations produced on a mill. Impeders and impeder booster pumps are available to minimize power used during welding and increase the efficiency of the welding process by ensuring that power is directed down the vee.
