    3Dsigns,

    I was at a foam supplier some years back and saw their large block cutter in action. They were using a constant current welder connected to the wires. They said they would just adjust the current depending on the number of wires.

    3Dsigns,

    I suggest that you add the Amp and Voltage meters. At least the Amp meter. for monitoring.

    I control the amps to my bow wire after I find what amps is needed by using foam scrapes. You will find that the amps for cutting the foam will be the same for 100 mm to 1.5 meter length of wire but the voltage to supply the amps will vary to wire length. I found that 1 to 1.75 amps is all that is needed depending on type of foam.

    I have a home built 50V supply using 2 10A transformer wire in series through a bridge for DC voltage and control by a light dimmer. I just the voltage to the transformers by the light dimmer until I have the amps that is needed for the cut.
