One of my mobile-radio-business's competitors was a nototious skinflint who sent his techies out on jobs with inadequate equipment; I remember watching one such trying to solder the centre of some coax outside in the wind using a car-battery-powered non-thermostatic soldering-iron of deeply inadequate power.

The techie had clearly come across the problem before because he had a jam-jar with a hole punched into the lid; he stuck the iron in through the hole to shield it from the wind and waited a while for the heat to build up.

Thermostatically-controlled soldering irons are brilliant in the field-service world; I'm sure their fast heat-up-to-soldering-temperature, saving several minutes per call and so letting the techie do more calls per day, soon pays for their greater cost over clockwork irons.
