This causes inflammation. Although some people with lupus have only mild symptoms, the disease is lifelong and can become severe.
Heat Settings for Fabrics. Use these basic iron temperature setting guidelines for your fabrics: acetate, 290 F; acrylic or nylon, 275 F; cotton, 400 F; linen, 445 F; polyester, silk or wool, 300 F; rayon, 375 F; triacetate, 390 F. For blended fabrics, use the lowest temperature recommended for the fibers in the blend.
There is no proper soldering iron temperature just for a given type of solder-the iron temperature should be set for both the component and the solder.When soldering surface mount components, a small tip and 600F (315C) should be sufficient to quickly solder the joint well without overheating the component.here is no proper soldering iron temperature just for a given type of solder-the iron temperature should be set for both the component and the solder.
