The APEX™ 2100 Controller is a fully integrated and synchronized system for controlling mechanical oscillation, torch height control (AVC) and wire and gas delivery. With the weld data delivered between the control and pendant instantly, the operator has immediate access to monitor, adjust and control weld parameters throughout the welding process. Simple menus for operation and intuitive controls allow the user to easily operate the system and produce consistent welds for a wide range of applications. The controller is designed to be quickly serviced in a production environment and to withstand harsh environmental factors.
