Digital input signals (signals from robot)
Signal level - LOW 0 - 2.5 V
- HIGH 18 - 30 V
Ground When connecting to the TIG-KD connection box:
GND Common = X3/pin 27
When connecting directly to the KD7000:
GND Common = X2/pin 27
All digital inputs are electrically isolated using optical couplers.
Start KD TIG-KD connection box:
Connection option direct to the KD 7000:
The "Start KD" signal starts wirefeeding at the specified wire speed when "Start Robot" is
selected on the "Wire-Mode" dip switches
IMPORTANT! If "Start TIG" mode has been selected on the "Wire-Mode" dip switches,
- it is not possible to start wirefeeding using the "Start KD" signal,
- wirefeeding starts when the welding current has reached the main current phase.
The main current phase takes place between the start current and final current phase
Arc on (Com-
mand arc on) TIG-KD connection box:
The "Arc on" signal starts the power source. The gas flow is controlled from the power
source. Therefore, the "Gas on" signal does not need to be additionally set.
Gas on (Com-
mand gas on) TIG-KD connection box:
The "Gas on" signal starts the "Gas test" function on the power source. The required gas
flow can be set on the pressure regulator on the gas cylinder.
The "Gas on" signal can be used to create an additional gas pre-flow during positioning.
