Signals for robot welding
General remarks Robot operation of PlasmaModule 10 requires a robot interface. PlasmaModule 10 can
be controlled via the following interfaces:
- Robot interface ROB 3000
- Robot interface ROB 4000
- Field bus

Overview
Signals for robot-controlled plasma welding operation and their function on the Plasma-
Module 10:
Welding start
starts the pilot arc
Robot ready / quick stop
24 V = Robot ready to weld / 0 V = quick stop; quick stop stops the welding process
immediately
Gas test
activates the Gas Test function on PlasmaModule 10
Welding simulation
The welding simulation signal allows a programmed welding path to be simulated; an arc
and shielding gas are not required.
Power input value
Specifies the plasma gas flow rate; 0 V = minimum plasma gas flow rate, 10 V = maxi-
mum plasma gas flow rate
Arc stable
The „arc stable“ signal is set as soon as a stable arc is present after the pilot arc has
ignited.
