NX welding problem

[Thescoe]

We have 2 NX dual EA1400N weld cells with Miller Auto Axcess 450s utilizing twin coordination. When 1 robot experiences a missing arc alarm in mid weld, the other robot stops moving but continues welding in place causing scrapped part, part welded to locator pin, massive downtime, yada,yada. This occurs in both cells. In all other similar weld cells (but not using twin coord) the other robot stops motion and arc. Am I missing a setup protocol of some kind? The only outward difference between these two cells and our other ones is the fact that they use twin coordinated programming.

I had something like this one time and retry was on in the aux weld file....

I checked this today. On one of the cells a few of the arc files had retry active so I disabled them. However I don't think this is the root cause. The other cell uses line instructions for arcon with no auxiliary condition and the problem still occurrs.

So you are saying that even after you have disabled the ARC retry the second robot still continues to weld?

[Thescoe]

Yes, no retry active. As stated the arcon instructions are line item i.e. ARCON, wire speed, and voltage only

We had a similar problem when using ARM interference. Turned out to be a ladder problem. We had two robots welding in one place for about an hour. It was cool.

Wow, you guys get long breaks
