Tweco HMC-410 Robotic Interface Kit - Manual (Page 21)

Pin Name Description
L Weld Amps
Feedback +
This line is a 0 to 10 VDC analog signal, which corresponds to 1.0 Volts
DC = 100 Arc Amps.
M Weld Amps
Feedback -
Analog return
N Wire Stick Ckt + Robot wire stick sensing input.
P Wire Stick Ckt - Robot wire stick sensing input return.
R Weld On/Off When the robot control shorts this line to 0 VDC Common, the HMC-410
will initiate a weld and continue it for as long as the voltage is present.
Once the short is removed, the weld is stopped. The parameters for the
weld are programmed in the PREFLOW, RUNIN, WELD (including
sub-segments), CRATERFILL, BURNBACK, and POSTFLOW
screens. Times for each segment are programmed on the HMC-410.
Voltage and Wire Feed Speed can be programmed locally on the
HMC-410, or remotely from the robot control. To use the remotely con-
trolled settings, set the appropriate parameter setting to EEE.
S Gas On When the robot control shorts this line to 0 VDC Common, the HMC-410
will purge the gas lines.
T Spare 24V Out-
put
U Wire Forward When the robot control shorts this line to 0 VDC Common, the HMC-410
will run the wire at the speed set in the INCH SPEED window on the
HMC-410. If EEE is selected for INCH SPEED, the speed will be set by
the voltage on pins E and F.
V Wire Reverse When the robot control shorts this line to 0 VDC Common, the HMC-410
will reverse wire at the speed set in the INCH SPEED window on the
HMC-410. If EEE is selected for INCH SPEED, the speed will be set by
the voltage on pins E and F.
