4.0  Controls: Switches, Foot Pedals and Touch Screen

 

This section introduces you to the various switches, foot pedals, touch screen that you use to 
control the weld setup and welding process. The following is an overview of these switches, 
foot pedals, touch screen and their layout. Many of the functions provided by these controls 
are discussed in greater detail in other sections of this manual. 

4.1  Description of Control Module Touch Screen & 
Switches  

This section describes the various controls located at the control module. The control module is 
attached to the upper beam where it is directly overhead and in front of the operator. As 
discussed in Modular and

 

Adjustable Features, the control module houses the SEAMTEK 36’s 

touch screen operator interface and is where most of the user control features are found. Here 
is a picture showing the main control screen.
