Display MoreHow have you been recovering from this error when you encounter it?
Have you performed a Cold Start?
Under MENU > SYSTEM > Config, what is Use HOT START set to?
or
What is the value of $SEMIOWERFL?
I could just restart my weld and it would continue on welding for a random distance and stop again. I did attempt to do a cold start and that didn't fix anything, the error still persisted.
I reached out to Fanuc technical support and this is what they send me after asking for a solution with the alarm TAST-004
QuoteI found a couple of variables in other TSL that resolved the alarm. Please set: $TG_MX_SCUS = 500 (it is presently set to 250). 2) Cycle power on the controller. Set the system variable $TG_SC_LEVEL = 0. Please let me know if you need anything else. Thanks and have a wonderful day
After they sent me this I did more research about the variable $TG_MX_SCUS. Apparently it has to do with the usage of the CPU for the controller. From the factory Fanuc limits the CPU and it was too much information to process for tracking.
Here is a link to another post about this variable
RE: AVC Instead of TAST in 120 ic
Go to system variables when in control start and to the following;
$AWECFG.$ARC_PROCESS
When value 1 = TAST
When value 2 = AVC
The variable beneath $AWECFG is $AWECFGS – which is individual config parameters for each welding procedure available to be set up.
All of the $ARC_PROCESS sub variables for each $AWECFG no's inside the header variable need changing to ensure tracking schedules change from TAST to AVC.

As of now this has fixed my issue. Thanks for your help!
