hello, Im looking for a temperture controller for my hotwire (profile wire shaper) powersupply is there any plans avail. for a diy unit, need a pulse circuit maybe a pwm?
My problem is the frist foot of the cut is really nice, ( the profile of the flate wire holds it shape good....) as i get furthur the wire gets hoter wire and develops foam resin from the cut .... i see small drops of foam resin burns in the neg half... i need for my molds.... i turned down the heat but i get drag and see the wire prophile deform...... anyone have a tempture controller that pluse on off
