So why was I struggling recently to solder my numerous projects, waiting for irons to heat up, only then to have too much heat , or worse too little , I managed for 60 years with an assortment of wattages !... I should have gone down the temperature controlled path long ago. I have looked in the past but it just didn't seem economic and the hefty look of the iron of most 'machines' put me off … I can report now I have an Antex 660A , ( I shopped around and got it for <100 GBP) no digital display just a basic control knob 200/480 c and a led. It has a comfortable small 'hot' end and performance so far, I cannot fault.. just need some 0.5 mm tips..
