Do I need a variable-temperature heat gun or will dual-setting work?

For most DIY tasks like shrink tubing, crafts, and basic paint softening, a dual-temperature gun is sufficient and cheaper. Variable-temperature models with LCD displays matter most for delicate work — electronics rework, vinyl wrap, and epoxy — where overshooting can ruin the workpiece. Specialist-community threads consistently recommend variable control if you plan to use the tool across multiple applications.
