Description
An Arc End weld schedule specified a time of 99.0 seconds. This time value is sometimes used with Arc Starts to indicate ramping during an entire motion. This type of ramping is not available for an Arc End. A time of 99.0 seconds for an Arc End craterfill time is very long and is not recommended. If a long time is needed then 98.0 seconds will work without this error.
Remedy · Remède
