Most (if not all) the Elecraft "auto tuners" will not tune unless
commanded by a tap of the TUNE button.
The "automatic" part means that once tuned, the tuner will remember the
L/C settings for that frequency and will return to it when you move the
VFO to that band segment.
That means that your transmission is not interrupted by the tuner
attempting to tune while you are transmitting.
The KXAT1 and KAT500 are the exception, if placed in "AUTO" it will
attempt to tune when it senses a high SWR. On SSB particularly, that
may initiate a false SWR reading. The instructions for the KXAT1 tell
you to "train the tuner" to your antenna and then change it to "MAN"
mode so it does not respond to those false SWR indications.

I can't speak for the K3, but my KX3 only tunes when I ask (push a
button) but my LDG is an auto tuner. I DO have a LDG AT-200 on my
Orion. I had another brand z 125 watt tuner and it fried when I ran
RTTY at 100 watts. I switched to the LDG and it does take the power.
After digging (much digging) I found tuner z was only good for about
60 watts key down. The KX3 also "burps" when I change bands - quick,
so I am not sure the problem with the K3.
The pushing a button is nice, but... I can set the LDG tuner to
automatically tune when the VSWR gets above a set-point. Nice, no
"need" to push a button. It will tune with full power drive. Auto
tune is nice. The first Orion's with the built in tuner (LDG) only
tuned when asked (push the button). One reason I went for the
external tuner for the Orion II.
