CHAPTER 1:  DESCRIPTION 

 

 

UNIFLOW

®

 2 PULSED THERMODE CONTROL 

990-228 

1-7

 

HEAT / NO HEAT Switch 

 

When this switch is in the 

HEAT

 position, the programmed profile can initiate 

heating energy. 

When you set the switch to the 

NO HEAT

position, no heating current can flow.  

This function is required to adjust a new thermode to the work pieces prior to 
initiating a heating cycle.
