Thanks Richard, had a look. They obviously have quality products. Just some comments.
The soldering irons are not 'temperature' controlled. They are 'volts or current controlled' and the electronics convert this into a temperature 'indicator' for a timed shut off or digital display of a calculated temperature. There is no mention at all about a thermocouple in the tip. Note the comment that the irons shut down after 10 mins to stop the tips burning out. Shouldn't really be necessary with proper temperature control.
The solders are very high melting point and free running. Their best selling grade (their words) say to set the iron for 390 deg C! No doubt lead free and very high silver content. Suspect ideal for model railways. Normal lead solder melts around half that value and can be made to be very runny or slushy depending on the iron temperature. A bit more useful when 'blacksmithing' a tin plate hull.
Nearly all fluxes these days are non acidic. The problem is finding the old fluxes. They did work very well.
