this thread was made quite long ago. i am in similar situation. curious if you had any issues with weld speeds? My weld speeds are set at 11.5 in the schedule. having to run approximately 220IPM using linear moves. while using coord and circle points im running 1.7-9 Ipm to achieve the proper speed. 4 inch diameter shaft with two flanges. three welds each requiring a different speed to achieve a 3/8 weld. have to time each rotation at about 70 seconds. ive had different lengths of the same part and the speeds are not consistent even from program to program. not even close. having a swing from 12 ipm all the way to 60 with coord and circle points.
