Ahh, ok. On my AX2 mod, I was getting good contact from the batt tube to the driver so didn't add any solder or anything. On other Amutorch mods I did, the stock driver had an extra brass ring and I used my hot air gun to remove and transferred it to the new replacement driver. I did that with the AX3 and AX4. I think I removed the one from the AX2 but decide not to use it. That contact point between the tube and driver shouldn't be getting much wear since it doesn't need to be opened to get to the battery.
AX4, brass ring removed:

Now transferred, with a little sanding down at the green mark to be sure no inadvertent contacts:
