Capacitive discharge power supplies are best for twin coil machines. Some people have burned up their twin coil machines by using just a 12 volt power supply. The switch arcs and sticks in the closed position.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
The Rix machines aren't going to be much different than the Kemtron units. Dual coil machines usually need a pretty good poke, especially if you are throwing more than one at a time.
A capacitor discharge unit will solve your supply problems.

Wow - How's THAT for three quick answers !!!

CD power supplies give one shot. release the switch and the capacitor charges up after you release the switch. Usually a CD power supply is ready within a couple seconds depending on the design. Some people switch a ladder of maybe six twin coil machines at one time. I use a spring loaded push button switch, push and release. Twin coil machines are very quick.
I have both RIX and Katsumi (imported by Kemtron, I bought mine from the source) twin-coil machines in service. Either brand will draw in excess of 2 amps. I don't use a CD circuit, but do have a 12.6 volt 3 amp dedicated power supply for switch machines only.
No matter whether you use CD or not, your electrical connection should be momentary. I use several, ranging in complexity from hot probe and studs to momentary-contact rotaries. Having a CD circuit continually connected to the coil of a switch machine defeats the purpose of using it in the first place.
