I’m trying to program a path where the torch head stays still and the positioner rotates the part (example path pictures). I’ve tried every combination in the Interpolate External Axis options and nothing seems to work. I’ve seen this done in the 3d printer PowerPac demo and was hoping it was possible with the Arcweld powerpac.
Sounds like you should look into multi move for a solution. You essentially have the work object that the weld robot is „following" being controlled by another physical entity which is moving so it sounds like you’ll need to employ multi move some how.

From your screenshot it seems that you are more experienced than me, so I say this with caution. But I would try this without the Interpolate External Axis. Obviously this is a possible move, it has been done in industry before so there has to be a way. If it works as a basic RAPID motion with the same TCP and different external-axis values, then the concept is valid. If it only fails in ArcWeld PowerPac, then the problem is probably the PowerPac workflow or station setup. It may just not like program structure.
Example:
Declarations
P1 some TCP location blah blah blah external axis angle 0
P2 same TCP location blah blah blah external axis angle 90
I’m assuming you probably are aware of this but thought id throw it out there.
Loganm is correct you copy and paste you starting robtarget, change the positioner angle to the finish angle and change it to an arc end command if required.
