SENSOR™ OHC - Oxy Height Control is an advanced automated height control system for
oxy fuel shape cutting applications. This product utilizes advanced capacitive sensing and
microprocessor technology to automatically detect the plate and adjust torch position to a
desired set point during oxy fuel cutting operations. This reduces operator input, improves
accuracy and increases productivity.
