This increases the surface area of the coil compared to a simple round-wire build, which can improve flavour and vapour production. The trade-off is a slightly slower ramp-up time compared to simpler coil types.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between KA1 and Ni80?\u003c\/h3\u003e\n\u003cp\u003eKA1 (Kanthal A1) is an iron-chromium-aluminium alloy commonly used for wattage-mode vaping. It has a slightly slower ramp-up than Ni80. Ni80 (Nichrome 80) heats up faster and is also used in wattage mode. Both are suitable for regulated devices. Neither should be used in temperature control mode.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use these coils in temperature control mode?\u003c\/h3\u003e\n\u003cp\u003eNo. KA1 and Ni80 are not suitable for temperature control mode. Use these coils in wattage mode only on a suitable regulated device.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need to check the resistance before vaping?\u003c\/h3\u003e\n\u003cp\u003eYes. Always check the completed coil resistance on a suitable regulated device or resistance meter before use. Never fire an untested build.\u003c\/p\u003e\n\n\u003ch3\u003eIs Firebolt Cotton included?\u003c\/h3\u003e\n\u003cp\u003eYes.

Whether you're building an MTL setup with the KA1 option or a DL rig with the Ni80 version, the Fused Clapton format delivers solid flavour and consistent performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShop Vapefly Firebolt Cotton + Fused Clapton Coils online from Coffee \u0026amp; Vape with free delivery on orders over R950 and nationwide delivery across South Africa.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: This product is intended for experienced users familiar with rebuildable atomisers, coil installation, Ohm's Law and battery safety.
