So if I use a dimmer switch on this transformer and not go over 4.8 volts, I'll be within the limits of the transformer. And then the question becomes 38 watts, and will it be enough to cut foam with this custom tool I made, probably not.
G'day Sean,
Use the dimmer on the primary side of the transformer, the high voltage side, start at the lowest setting & adjust up, until the wire is hot enough, it has worked for me.
We use 240 volts here in Aus, but your dimmers will work the same way, on 110 volts.
Light or electronic fan dimmers work well.
