The FP-300 Water-Soluble Flux Pen utilizes a spring-loaded applicator tip to deliver a controlled amount of flux to the work surface. The user friendly pin-point application is ideal for touch-up and light assembly work. To apply, simply depress the tip of the flux pen against the work area to start the flow to the applicator tip.
Each pen contains 10 grams of liquid flux. Unopened flux pens have a shelf life of 6 months. Flammable liquids should be stored in a dry, well ventilated environment away from open flames, sparks or direct heat.
