Any specific alarm you're getting??
-
No any alarm accrued on the TP -
Is this controlled by a PLC? Also, which welding power source are you employing?
-
Fanuc robot 100 iC with Lincoln power weve ,Fedder ( 4R 100)
-
In the weld Inputs do you have Arc Enable assigned?

Please somebody help :Our Fanuc Arc mate 100ic during welding time not performing the weld start during welding on time.Let me get it straight. Are you trying to say that your robot doesn't perform an arc start or is it starting an arc but not on time, like with delay?
-
Can you please write us how I can the weld Inputs do the Arc Enable assigned.
-
Menus-->IO-->WeldIO, choose inputs, look for arc enable.
-
I have do Arc enable but problem is same
-
Looks like your power wave is not connected. Whether the wire feeding is happening in manual??

Hello everyone,
I guess I have exactly the same problem.
The robot model is AM120iC with R-30iB controller. There is a plasma-cutting machine connected to the robot via Fanuc Model A IO modules. It is configured as General Purpose TIG (Amps) power source. I have configured the following signals:
- Current output (AO1)
- Arc Start output (DO1)
- Gas Start output (DO1, same as Arc Start)
- Voltage input (AI1)
- Current input (AI2)
- Arc Established input (DI1)When I execute the test program (just a simple cut), it works exactly as if Weld Enable was set to OFF - the robot does not send the Arc Start signal and is not waiting for the Arc Established signal. Just ignores the power source, without any errors... I have checked the whole Weld System and Weld Equipment configuration (Arc detection enabled, Weld from TP enabled), everything seems to be fine.
However, when I program the signals "manually" (move to startpoint, set Arc Start to ON, wait for Arc Established, move to endpoint, set Arc Start to OFF) - everything is fine. This is of course very unsafe, but shows that the IO modules are connected and configured properly, it's just ArcTool that ignores them.
I have tried different options, like changing the power source type in Ctrl Start and then switching it back to General Puprose TIG (Amps), configuring more welding IOs etc. Nothing helps...
Any ideas?
EDIT:
Just for test, I have reconfigured the Weld IOs from DIOs to RIOs - and then the robot sets the Arc Start RO and waits for the Arc Established RI

Ok, I figured it out. There is a strange remark in the ArcTool manual, which says:
QuoteIf a controller connects a weld equipment ArcTool doesn’t provide the model
through digital I/O board like DeviceNet and Profibus et.al. please go through the
following procedures.
1. Set $AWEPRR.$VENDOR_ID to 108 manually. If the setting is incorrect,
“ARC-045 Weld EQ is OFFLINE” alarm will occur.
2. Set required weld I/O manually refer to Procedure 12-11. If the settings are
incorrect, “ARC-040 EQi Missing I/O” alarm will occur.This is not English, nor correct... Because it seems that the IO Links is also considered as "not provided" - setting this $AWEPRR.$VENDOR_ID variable to 108 helped! But as I have mentioned earlier, there were no errors, the robot just ignored the Arc Start and Arc End instructions...
