Thin-Gauge Hot Wire Machine Cutting Wire. Because of the Inconel's sensitivity to heat, it takes less power to make it perform quickly and smoothly in EPS. Inconel hot wire leaves a very narrow curf.
Note: Heated Wire expands when hot. If the spring is too tight the wire may break restricting operation of mechanism. If too loose, the cut will be sloppy. Readjustment of tension may be necessary from time to time.
Power Controller – Use nothing longer than a 50 foot 12/3 grounded extension cord. Set the temperature dial on the controller to zero (0). Turn on the hot wire power controller and adjust the dial until the wire glows orange. Immediately back off the controller until the heated wire just begins to turn from orange to gray. This is the optimum foam cutting temperature of the wire. Anything hotter will cause premature wire failure or anything cooler will require too much feed pressure on the wire causing premature failure. If the wire is too hot, the cut may not be as accurate as you would like. A wire that is too hot will melt the foam too quickly at the beginning of the cut and less quickly as the wire cools off resulting in an inaccurate cut.
Use only the recommended wire.
Do not use this equipment in wet or damp conditions.
Use only grounded receptacles.
