Process Controller PEK

The following items have been added to your list


PEK is a system adapted for use with ESAB’s automatic power sources LAF 631/1001/1251/1601, TAF 801/1251, and Aristo® 1000 AC/DC. The control system is connected to the power source via a control cable and incorporates a CAN bus system for data transfer.

PEK can also be used as a motion controller to integrate other power sources for mechanisation and automation.

The control system is easy to use thanks to its clear text menu. Users can choose between a large number of different languages. The large display keeps the user informed about the main parameters including current, voltage and travel speed. Parameter sets can be given names for easier assignment.. Five soft keys can be configured according to individual preferences. PEK supports your system’s maintenance and keeps track of its use.

ESAB standard motors and travel axis can be selected from a list, and other motors can be programmed manually.

PEK can easily be pre-set by the user. Manual control keys for wire feed and travel direction allow fast access to frequent settings. Turn knobs allow easy adjustment of wire feed speed, voltage and travel speed during the process.

Additional functionality
More functions are available by adding an external analogue or digital interface.

Welding parameter limits
PEK allows defined limits for the settings and the measured parameters. The welder will be alerted if the weld parameters are outside the allowed limits.

Makes welding safer and easier
A USB slot enables users to file all settings and configurations. Restore your valuable production data within minutes. Security is provided by three-level user accounts. Users can also transfer welding parameters between other PEK units.

Emergency stop button
The emergency stop button can also be used in an extended E-stop chain.
