The main current signal is set between the starting current and final current phases.

The robot welding torch will normally have a cut-off switch. In the event of a collision, the
contact in the cut-off switch opens and triggers the LOW active “Collision protection”
signal.
The robot control must shut down the robot immediately and stop the welding process
using the “Quick stop” input signal

Pin X2/14.................... 24 V signal
Pin X7/2 or X12/2....... GND
The “Power source ready” signal remains on as long as the power source is ready to
weld.
The “Power source ready” signal is reset whenever an error occurs in the power source
or the robot control sets the “Quick stop” signal.
The “Power source ready” signal can therefore be used to detect internal errors and
errors in the robot.
