We have an AMI 307 orbital welding system with an 8-4000 weld head.
For some reason, the speed calibration freaked out + it was going two orbits. I ran auto calibrate, and it went back to 1 orbit, but the speed is off. Now it appears the only way to get it back to "normal" is to run it timed with a stopwatch and adjust a trim pot.
Anyone else have similar problems? How often should this system be "calibrated"? I would not expect it to "drift" or change. We have about 60 weld procedures that I don't want to keep requalifying. The operator also scrapped a $2000 part when he did not know it was out of calibration. It could be one of those freaky Windows OS problems too. It has done that in the past, and the problems went away as mysteriously as they dissappeared. The system is only a year or two old. Anyone else with this system, be warned.
