- How much current will I need to accomplish this? I have a few 240VAC - 12VDC 3A transformers but will that have enough juice? I don't need it to heat up as quickly as in a car, but I don't want to be waiting too long either.
How could I go about controlling the temperature? I figure a pot. would do the trick but I'd have no idea which pot. to buy or if I'd need any other components on top of that. Makes it difficult when I have no idea what gauge the nichrome wire is in the cig. lighter.
Also, I have a 12VDC 4A transformer but I replaced the 0.5A fuse (blown) with a 4A fuse and sparks started flying from the windings/core as soon as I switched it on (not under load). The guy at the electronics store said a 4A fuse would be fine so perhaps the transformer is faulty.
